An electron experiences a magnetic force of magnitude` 4.60 xx 10^-15 N`, when moving at an angle of `60^@` with respect to a magnetic field of magnitude `3.50 xx 10^-3 T`. Find the speed of the electron.

Text Solution

Verified by Experts

`:'F=Bqsintheta`
`:.v=F/(Bqsintheta)`
`=(4.6xx10^-15)/(3.5xx10^-3xx1.6xx10^-19xxsin60^@)`
`=9.47xx10^6m//s`
