Question

The work done in bringing a unit positive charge from infinite distance to a point at distance x from a positive charge Q is W. Then the potential at that point is

Answer 1

Answer:

WQ since V=W/q ......................

Explanation:

Answer 2

Answer:

the potential at that point is W (Option B).

Explanation:

Potential at a point is defined as work done required to move a point charge from infinity to the observable point.

The convention is that at infinity the potential is zero, hence it is always compared with infinity.

The formula for the same is:

W= q.V

Here according to the question, charge(q) = 1 C

So, potential (V)=  $\frac{W}{1}$ = W

Therefore, the potential at that point is W.
