An isolated positive point charge \(+Q\) is fixed in space. Point \(P\) is located a distance \(r\) from the charge, with the electric potential defined to be zero at infinitely far distances (\(V(\infty) = 0\)). What is the electric potential \(V\) at point \(P\), and what is the sign of the work done by the electric field as a small positive test charge \(+q_0\) is moved from infinity to point \(P\)?
