Question

The potential at a point is 20 v. the work done to bring a chargeof 0.5 from infinity to this point will be

Answer 1

Hey friend

here is your answer

electric potential ( v ) = 20 volt
charge ( q ) = 0.5 c

work done ( w ) = ? ( to find )


as
$v = \frac{w}{q} \\ w = v \times q \\ w = 20 \times 0.5 \\ w = 10 \: joule$


so the work done in 0.5 from infinity to a point of potential 20 V is 10 joule.


glad to help you
