Assertion (A): When reverse voltage across a p-n junction is increased, the junction capacitance decreases.

Reason (R): Capacitance of any layer is inversely proportional to thickness.

Assertion (A): If an atom of polarizability a is placed in homogeneous field E, the energy stored is 0.5 aE².

Reason (R): Capacitance of an isolated conducting sphere R in vacuum is 4 p∈₀ R farads.
