A semicircular arc is shown around a point charge q. What will be the work done in transferring a test charge `q_(0)` from A to B?

Text Solution

Verified by Experts

Two points A and B are at the same distance from the charge, so potential will be same at points A and B, so work done will be zero.
`(therefore W_(AB) = V_(B)-V_(A)=0)`
