Question

A positive charge is moved from point A to point B along an equipotential surface. How much work is performed or required in moving the charge? A positive charge is moved from point A to point B along an equipotential surface. How much work is performed or required in moving the charge? Work is required in moving the positive charge from point A to point B. No work is performed or required in moving the positive charge from point A to point B. Work is performed in moving the positive charge from point A to point B. Work is both performed and required in moving the charge from point A to point B. SubmitRequest Answer Provide Feedback Next

Answer 1

Answer:

No work is performed or required in moving the positive charge from point A to point B.

Explanation:

Lets take

Q= Positive charge which move from  point A to point B along

Voltage difference,ΔV =V₁ - V₂  

The work done

W = Q . ΔV

Given that  charge is moved from point A to point B along an equipotential surface.It means that voltage  difference is zero.

ΔV = 0

So

W = Q . ΔV

W = Q x 0

W= 0 J

So work is zero.
