NEETPhysicsElectrostaticsMCQ+4 / −1
The diagrams below show regions of equipotentials.

NEET 2017 Physics - Electrostatics Question 70 English
A positive charge is moved from A to B in each diagram.
  1. A
    In all the four cases the work done is the same.
  2. B
    Minimum work is required to move q in figure(I).
  3. C
    Maximum work is required to move q in figure (II).
  4. D
    Maximum work is required to move q in figure (III)
View written solutionFree

Correct answer: A

As the regions are of equipotentials, so Work done W = qΔ\Delta ΔV

Δ\Delta ΔV is same in all the cases hence work - done will also be same in all the cases.
