Question

An electron of mass m and charge e is accelerated from rest
through a potential difference V in vaccum. The final speed
of the electron will be
(a)√eV/m
(b) v√e/m
(c)√ 2eV/m
(d) 2eV/m
the​

Answer 1

Answer:

hello

Explanation:

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 =  

Correct option is C
