Potential energy

Question

4 x 10²⁰ eV energy is required to move a charge of 0.25 coulomb between two points. What will be the potential difference between them?

Easy

A

178 V
B

256 V
C

356 V
D

None of these

Solution

$By using KE = QV \Rightarrow 4 \times 10^{20} \times 1.6 \times 10^{- 19} = 0.25 \times V \Rightarrow V = 256 volt$
