Question

If `4 xx 10^(20)eV` energy is required to move a charge of `0.25` coulomb between two points. Then what will be the potential difference between them ?
A. `178 V`
B. `256 V`
C. `356 V`
D. None of these

Answer 1

Correct Answer - B
By using, `KE = QV rArr 4 xx 10^(20) xx 1.6 xx 10^(-19)`
`= 0.25 xx V rArr V = 256` volt
