Question
A positively charged body ′A′ has been brought near a neutral brass sphere B mounted on a glass stand as shown in the figure. The potential of B will be:
Options
A.Zero
B.Negative
C.Positive
D.Positive
Solution
Potential of B = Potintial at the centre of B
= Potential due to induced charges + potential due to A.
= 0 + (+ ve) ⇒ Potential of B is +ve.
= Potential due to induced charges + potential due to A.
= 0 + (+ ve) ⇒ Potential of B is +ve.
