Question

By the definition of electric potential, the work done to bring a unit positive charge from infinity to a point P equals:

Options

• \[qE(P)\]

• \[U(P)\]

• \[qV(P)\]

• \[V(P)\]

Answer 1

By definition, the electric potential at P equals the work done to bring a unit positive charge from infinity to P. For a general charge q, this work scales by a factor of q, giving \[qV(P)\].
