Question

12) Calculate the angular momentum of an
electron revolving round a nucleus in a
circular orbit of radius 5x10-11m with a
velocity of 2x106ms-1. If the mass of
electron is 9x10-31 kg, calculate the
angular momentum of the electron.​

Answer 1

Answer:

9 x 10^-35

Explanation:

Angular momentum =mvl

M=9 x 10^-31

R=5 x 10^ - 11

V = 2 x 10^6

=> (9 x 10^-31) x (5 x 10^-11) x (2 x 10^6)

90 x 10^-36

9 x 10^-35 answer
