Two small sphres of radius 'a' each carryig charges `+q` and `-q` and placed at points A and B, distance 'd' apart. Calculate the potential difference point A and B.

Text Solution

Verified by Experts

The correct Answer is:
`2 q//4 pi in_(0) d`
Potential between A and B `= V_(A) - V_(B)`
`= (1)/(4pi in_(0)) xx (q)/(d) - (1)/(4pi in_(0)) ((-q))/(d) = (2q)/(4pi in_(0) d)`
