Question

If an earthed plate is brought near positively
charged plate, the potential and capacity of
charged plate.
A
Increases, decreases
B
decreases, increases
с
decreases, decreases
D
increases, increases​

Answer 1

Answer:

I guess the answer is B. Decreases, increases

Explanation:

When we bring a earthed plate near positively charged plate, negatiive charge is induced on the earthed plate.

Because of this negative charge, potential of positive plate decreases. 

We know Q=CV

So, for constant charge (Q), as V decreases, C increases.
