Question

31/90 If the magnitude of charge on electron
ind proton is increased by two-folds, then velocity of
he electron moving in Bohr orbit of H-atom
Increases by 4 times
Decreases by 2 times
Increases by 8 times​

Answer 1

Dear Student,

◆ Answer -

Velocity of electron decreases by 2 times if charge on the epectron is halved.

● Explanation -

Velocity of the electron moving in the Bohr's orbit is inversely proportional to charge on the electron.

v ∝ 1/q

Therefore, if charge on electron is halved, its velocity will 2 times the original velocity of electron.

Thanks dear. Hope this helps you...
