In Fig . `V_(0)` is the potential barrier across a p-n junction, when no battery is connected across the junction

Options

A. 1 and 3 both correspond to forward bias of junction
B. 3 corresponds to forward bias of junction and 1 corresponds to reverse bias of junction
C. 1 corresponds to forward bias and 3 corresponds to reverse bias of junction
D. 3 and 1 both correspond to reverse bias of junction

Answer

b

Explanation

Given `F=(GMm)/(r^(2))`
M= effective mass of hydrogen atom
= mass of electron + mass of proton `=(B^(2))/(C)`
where B is BE of hydrogen atom = 13.6 eV
