Aproton is accelerated down a uniform electric field of 450 n/c. calculate the acceleration of this proton.

The acceleration of proton will be

Explanation:

We have given electric field E = 450 N/C

Charge on proton

Force on electron due to electric field is given by

Mass of electron

Now according to second law of motion

So

So the acceleration of proton will be

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
