Question

Energies required to knock the electrons out of the various shells of Ni atom are
K - shell 1.36×10−15J
L - shell 0.16×10−15J
M - Shell 0.08×10−15J
The minimum accelerating potential for emission of K-radiation from an X-ray tube with Ni as target will be

Answer 1

Explanation:

1.6x

${10}^{ - 19}$

x p.d = 1.36x10^-15

pd =1.36x10-15/1.6x10^-19

8.5 kv is answer
