Question

Draw lines of force to represent uniform electric field

Answer 1

Electric lines of force are imaginary line or curve drawn in Electric field in such a way tangents to it at any point gives the direction of electrostatic force. It represents the strength and nature of electric field at any point due to a charge.
higher the Electric lines of force per unit area , higher will be electric field strength .

Uniform electric field means electric lines of force are uniformly distributed. As I attached a rough daigram of uniform electric field. here all lnes of force are parallel and equidistant from each other.
