In the above figure an uncharged conducting plate B is brought near A (left side of A)
What will happen to plate B?
b. What will happen to the deflection `theta_(0)`
c. If the plate B is earthed, what will happen to the potential and capacitance of plate A?

Text Solution

Verified by Experts

a. Induced charges appear in B
b. Effect of induced charge is to reduce the field of A, hence deflection of e of the electroscope decreases.
Potential decreases and capacitance increases.
