Question

500 joule of work is done in moving a charge 10 micro coulomb from infinity to point P. What will be potential at point P?​

Answer 1

Given that,

Work done = 500 joule

Charge = 10 μC

We need to calculate the potential at point P

Using formula of potential

$V=\dfrac{W}{Q}$

Where, W = work done

Q = charge

V = potential

Put the value into the formula

$V=\dfrac{500}{10\times10^{-6}}$

$V=50\times10^{6}\ V$

$V=50\ MV$

Hence, The potential at point P will be 50 MV.
