What is the total amount of work required to
move a proton through a potential difference of
100. volts?
(1) 1.60 × 10^–21 j (3) 1.00 × 10^2 j
(2) 1.60 × 10^–17 j (4) 6.25 × 10^20 j

Explanation:

Work done to move a charge through a given potential difference is

here

q = magnitude of charge

= potential difference

here it is given that charge of the particle is same as charge of proton

now we have

he made 11 calls in one day

e/c, where e is its total energy
