When two electrons enter into a magnetic field with different velocities , they defect in different circular parts , in such a way that radius of one path is double that of the other. `1xx10^(7)ms^(-1)` is the velocity of electron in smaller circle of radius `2 xx 10^(-3)m`. The velcoity of electron in the other circular path is:

A

`4xx10^(7)ms^(-1)`

B

`2xx10^(6)ms^(-1)`

C

`2xx10^(7)ms^(-1)`

D

`2 xx 10^(6) ms^(-1)`

Text Solution
