W= 4 x 1020 eV. Q = 0.25C Using equation (1) We can convert the current value of W to Joules (Reason: Joules is the unit of Work Done) W = 4 x 1020 eV x 1.6 x 10-19 W = 6.4 x 10 W = 64J --------------------> (2) Substitute the Value of W from equation (2) and find V Q = 0.25 (given) V = W/Q V = 64 / 0.25 V = 256 Volts Hope this helps!
