3. What is the work done in carrying a 10 ue charge
from one point to another on an equipotential
surface
Answers
Answer:
Given:
Charge to be moved = 10μC.
Path along which charge has to be moved is along an equipotential surface.
To find:
Work done in that case
Concept:
Equipotential surface is that kind of surface in which the potential of a charge at any point on that surface will be same.
Equipotential surfaces are located at right angles(90°) to the electric field lines.
Calculation:
We know that , work done in an Electrostatic field will be equal to the change in potential energy between the 2 points.
So final answer :
Note: Potential on equipotential surface is same for a charge at any point.
From the above problem,
We've been provided with the charge of 10 micron C.
Work done is equal to the change in Potential Energy and potential energy will be equal the product of charge and change in potential.
Since, the potential is same, so Δpotential = 0.
Therefore,
Work done = charge * Δ potential
= charge * 0 = 0
Hence, work done is zero.
