Question

The sketch shows equipotential surfaces between two charged conductors shown in solid black. Points on the equipotential surfaces near the conductors are labeled A, B, C....L What is the direction of the Electric Field at point G? Towards I Towards F Towards H Towards E In the equipotential diagram on the previous question, suppose there is a negative charge at point G. In what direction would you need to push the charge so as to increase the electrical potential energy of the system? Toward F Toward Toward H Toward E

Explanation / Answer

solution:

1)Electric field E =-dV/dr

that means electric field points towards the decreasing direction of potential

so ans is towards i ans

2) work done = electric potential energy =q(dV) =-ve(-ve) ; q negative

change in potential shoud be -ve for increase potential energy of the system

so ans is towards I ans
