Question

the work done in bringing 5C of charge from infinity to a point A near a charged body is 20J. Find the potential at point A?

Answer 1

given,
charge=5c
work done=20j
p.d=j/c
p.d=20/5
p.d=4v

Answer 2

The potential of the point will be 4 volt

Potential

The electric potential at a point in an electric field is defined as the amount of work done in moving a unit positive charge from infinity to that point along any path when the electrostatic forces are applied.

The unit of potential is volt.

Formula

$W=vq$

Given

charge$q=5 C$

Work done, $w=20 J$

Solution

Relation between potential and workdone W=vq

Substitute the given values

W=vq

$V=\frac{w}{q}=\frac{20 J}{5 C}=4 V$

Hence potential of the point is 4 volt.
