A charge `2 mu C` is taken from infinity to a point in an electric field, without changing its velocity, if work done against electrostatic forces is `-40 mu J` then potential at that poin is?

Text Solution

Verified by Experts

`V=W_("ext")/(q)=(-40 muJ)/(2 mu C)=-20 V`
Note : Always remember to put sign of W and q.
