Question

A bullet of mass 2 g is having a charge of 2μC.
Through what potential difference must it be
accelerated, starting from rest, to acquire a speed
of 10 m/s?
(a) 50 V (b) 5 kV
(c) 50 kV (d) 5 V

Answer 1

Explanation:

As Workdone =q×Potenital diff(V)

also change in kinetic energy =work done

KE=qV
