The electric potential at the surface of an atmoic nucleus `(Z = 50)` of radius `9.0 xx 10^(-13) cm` is

A

`80` volts

B

`8 xx 10^(6)` volts

C

`9` volts

D

`9 xx 10^(5)` volts

Text Solution

Verified by Experts

The correct Answer is:
B
`V = 9 xx 10^(9) xx (50 xx 1.6 xx 10^(-19))/(9 xx 10^(-15)) = 8 xx 10^(6) V`
