Question

the electric potential at a point near isolated positive charge is
a. zero
b. infinity
c. positive
d. negetive​

Answer 1

Answer: c. positive

Explanation:

Going by the definition , electric potential is defined as the work done in bringing a test (positive) charge to that point, from infinity.

So, if we bring a test charge near an *isolated positive charge*, then we have to work against the field, to overcome the repulsive force.

Hence, work has to be done by external source, so work done is positive.

Hope this helped you.

So we have to put in energy in the process
