Question

what is the work done in moving charge 10nc between two points a and b separated by 20 cm on an equipotential surface

Answer 1

Answer:

zero

Explanation:

work done on a equipotential surface is zero

Answer 2

Answer:

Equipotential surface is the surface where potential remains constant. means, potential difference between two points on equipotential surface equals to zero.

e.g., ......(1)

we know, workdone = charge × potential difference

= 10 C × 0v

= 0

hence, workdone to move charge 10c between two points in equipotential surface = 0 J

here is the correct answer please mark me brainliest and give thanks
