Question

A charge of $10$ C is brought from infinity to a point near a charged body and in this process, $200$ J of work is done. Calculate the electric potential at that point near the charged body

• A. $20$ V
• B. $10$ V
• C. $5$ V
• D. $15$ V

Answer 1

The correct option is A $20$ V

Electric potential at at point is defined as the work done in bringing unit positive charge from infinity to that point.

$V=\frac{W}{q}$

$⟹V=\frac{200}{10}$

$⟹V=20J{C}^{-1}=20V$

Answer-(A)
