What is the physical meaning of the electric field?

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

What is the physical significance of electric field intensity?

Calculations of electric field intensity are of tremendous importance due to the technological applications of electric forces. It helps in finding the electric force experienced by a unit positive charge when placed at a point in the system of multiple charges.

What is an electric field in your own words?

An electric field is a region of space around an electrically charged particle or object in which an electric charge would feel force. … The lines are defined as pointing radially outward, away from a positive charge, or radially inward, toward a negative charge.

What is the physical difference between the electric force and the electric field?

A force that causes motion in those other interacting objects. A field is a way to explain how forces can be applied without physical touch. A charge is pulling in something else with an electric force without touching it – the “stuff” that connects the charge with its force through empty space is the electric field.

What is the meaning of physical significance?

Basically, “physical significance” is a fancy term for “definition”. Another way of looking at it is imagining you have an object or system and you want to measure some property; what exact physical characteristics do you need to measure to calculate this property?

What is electric field Class 12?

Electric field is a force produced by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field. … Electric field due to a charge at a point is the force that a unit positive charge would experience if placed at that point.

What are electric field lines Class 12?

An electric field line is an imaginary line or curve drawn from a point of an electric field such that tangent to it (at any point) gives the direction of the electric field at that point.

What is electric field in chemistry?

In atomic physics and chemistry, for instance, the electric field is the attractive force holding the atomic nucleus and electrons together in atoms. It is also the force responsible for chemical bonding between atoms that result in molecules.

What is electric field and electric force?

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

What is the difference between electrostatic field and electric field?

In general field produced by electric charge is called electric field but when electric field is produced by stationary charge it is called electrostatic field. For example, electric field produced by a moving charge and oscillating electric fieldin electromagnetic waves can not be termed as electrostatic fields.

What is the main difference between forces created by electric fields and forces created by gravitational fields?

They both act between two bodies without any means of contact. However gravitational force acts on mass while the electric force acts on charge. Gravitational force are only attractive while electric field can be attractive/repulsive. Electric field is much stronger than gravitational field.

What does physical torque mean?

Torque is the turning effect of force. And its physical significance are,Torque is the cause and angular rotation is the effect. … It requires lesser force to open a door by applying force at the farthest point from fixed end rather than applying force nearer to fixed end.

What is the physical significance of energy?

Energy is not a physical property. It is an abstract mathematical quantity that turns out to be very useful to calculate because it tells you important information about the state of the system.

What is the physical significance of curl of a vector field?

The curl of a vector field measures the tendency for the vector field to swirl around. Imagine that the vector field represents the velocity vectors of water in a lake. If the vector field swirls around, then when we stick a paddle wheel into the water, it will tend to spin.
