Electrostatics Question 6
Question 6 - 2024 (27 Jan Shift 2)
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 $(\mathrm{R})$ : 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 :
(1) Both (A) and (R) are correct but (R) is not the correct explanation of (A)
(2) $((A)$ is correct but $(R)$ is not correct
(3) (A) is not correct but $(\mathrm{R})$ is correct
(4) Both (A) and (R) are correct and (R) is the correct explanation of (A)
Show Answer
Answer: (4)
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 .
