The Electric Potential At The Surface Of An Atomic Nucleus Physics Question

The electric potential at the surface of an atomic nucleus (z=50) of radius 9.0×10⁻¹³ cm is

Options

(a) 80 volt
(b) 8×10⁶ volt
(c) 9 volt
(d) 9×10⁵ volt

Correct Answer:

8×10⁶ volt

Explanation:

V = (1 / 4πε₀). q/r

= [9 × 10⁹ × 50 × 1.6 × 10⁻¹⁹] / 9 × 10⁻¹⁵

= 8 × 10⁶ volt
