Given below are two statements : one is labelled a Assertion (A) and the other is labelled as Reason(R)
Assertion (A) : Work done by electric field on moving a positive charge on an equipotential surface is always zero.
Reason (R) : Electric lines of forces are always perpendicular to equipotential surfaces.
In the light of the above statements, choose the most appropriate answer from the options given below
Select the correct option:
A
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
B
((A) is correct but (R) is not correct
C
(A) is not correct but (R) is correct
D
Both (A) and (R) are correct and (R) is the correct explanation of (A)
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Electric line of force are always perpendicular to equipotential surface so angle between farce and displacement will always be $90^{\circ}$. So work done equal to 0 .
