Electrostatic work \(W\) is done on a charged particle as it travels \(10 \mathrm{~mm}\) along a straight path from point A to point \(B\) in an electric field. If you return the particle to point \(A\) and then exert a force on it to move it from \(A\) to \(\mathrm{B}\) along a curved path that is \(20 \mathrm{~mm}\) long, how much electrostatic work is done on the particle relative to the work \(W\) done along the straight path?
