Assertion: Capacity of a parallel plate capacitor increases when distance between the plates is decreased.
Reason : Capacitance of capacitor is inversely proporational to distance between them.

Options

A. chances of electrical break down will increases if potential difference between the plates is kept constant.
B. chance of electrical break down will decreases if potential difference between the plates is kept constant.
C. chance of electric break down will increases if charge on the plates is kept constant
D. chance of electrical break down will decrease if charge on the plate is kept constant.

Answer

A

Explanation

When charge on plate is constant electric field remains constant`E=Q/(2Aepsilon_(0))`
In case when potential difference is constant E=V/d
Electric field increases when 'd' decreases and hence chances of breakdown increases.
