Question

An electron of mass ’m’ and charge ’e’ is accelerated from rest through a potential difference ’v’ in vacumm. Its final speed will be​

Answer 1

Answer:

As we know,

Work done = eV

Where e : Charge on electron

           V :  Potential Difference

 

Since this work done is in the form of kinetic energy,

Hence,

v =  2eV/m
