Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible.
Why do electric field lines not intersect?
Electric field lines always point in one direction, at any point. When two lines intersect each other, tangents are drawn at that point indicating two directions of electric field lines, which is impossible therefore electric field lines cannot cross over each other.
Can two electric field lines intersect?
Electric field lines cannot cross. If they did, they would be telling you that the force on a charge at that location would point in two different directions, which does not make any sense at all. … Note: It is possible for two lines representing the same potential to cross.
Why two electric lines of force never intersect each other can two equipotential surface intersect?
Electric lines of force never intersect each other because. … Equipotential surfaces cannot intersect each other because two different equipotential surface have different electric potential, so if they intersect then the point of intersection will have two different potentials at the same point which is not possible.
When can electric field lines cross?
Field lines can never cross. Since a field line represents the direction of the field at a given point, if two field lines crossed at some point, that would imply that the electric field was pointing in two different directions at a single point.
Why do two contours never intersect each other?
Two contours never intersect each other because each line represents a separate elevation, and we can’t have two different elevations at the same point.
Why two field lines never cross each other at any point explain?
If two lines intersect at a point, then the tangent drawn there will give two directions of force, which is not possible. Hence two field lines cannot cross each other at any point.
Why electric lines of force are continuous?
(a) An electrostatic field line is a continuous curve because a charge experiences a continuous force when traced in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump from one point to the other. … Hence, two field lines never cross each other.
What does q1 q2 signify in electrostatics?
Given that the charge q1, as well as the other charge q2, is equal to zero. The equation indicates that one charge is positive and the second is negative. The magnitude of both charges is equal. This means the two given charges on the system in totality will account for zero.
Can electric field lines intersect in free space?
Electric field lines never intersect. … If the electric field in a given region of space is zero, electric field lines do not exist. The tangent to a line at any point gives the direction of the electric field at the point. Also, this is the path on which a positive test charge will tend to move if free to do so.
Why do two magnetic lines of force never intersect each other?
The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point.
Why the electric field lines do not form closed loops?
If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. … Therefore, we say electrostatic field lines never form closed loops.
Can two equal potential surface intersect each other?
No, it is not possible for two equipotential surfaces to intersect. This is because if two equipotential surfaces intersect, then there will be two values of potential at the point of intersection, which is not possible.
Can two different Equipotentials intersect one another Why or why not?
Can two different equipotentials intersect one another? Why or why not? No they could not because potential lines are parallel and always go from high potential to low potential. E=deltaV/deltaX equal zero.
Can lines of force cross?
Lines of force represent the strength of the electric field at any given point. … Therefore the lines representing the field cannot cross each other at any given location in space.
What does it mean when the electric field lines are close together?
A line tangent to a field line indicates the direction of the electric field at that point. Where the field lines are close together, the electric field is stronger than where they are farther apart.
