An `alpha`-particle of mass `6.65xx10^-27kg` is travelling at right angles to a magnetic field with a speed of `6xx10^5ms^-1`. The strength of the magnetic field is `0.2T`. Calculate the force on the `alpha`-particle and its acceleration.

Answer

`5*77xx10^(12)ms^-2`

Explanation

Acceleration, `q=(Bqv)/(m)=(B(2e)v)/(m)`
`:.` Charge on `alpha`-particle is twice that of proton.
