• electric force per unit charge

•  ratio of the charge of an object to its mass.

• change in force over time

Pick the true statements about electric field lines

• the field lines should never crossover

• the no.of field lines depends on the charge

• the field lines are stronger when they are close to each other

• all of these

What does affect the magnitude of an electric field?

• The magnitude of the test charge.

• Both the magnitude of the point charge and the distance of the point from the point charge.

• Only on the magnitude of the point charge.

• Only on the distance of the point from the point charge.

The direction of electric field intensity at a point due to a negative charge is

• perpendicular to the line joining the point and the charge

• inclined to the line joining the point and the charge

• radial and towards the charge

• radial and away from the charge
