(a) If the electrostatic work done on a charged particle as it moves around a closed path is zero, does this also mean that the electrostatic work done on the particle is zero as it moves along a piece of the closed path?

(b) In Checkpoint \(25.3 a\) we found that the electrostatic work done on the particle is the product of the \(x\) components of the electric force and the force displacement. Is the same true for the electrostatic work done on a particle that is moved along path \(\mathrm{AB}\) in Figure 25.6c?

(c) What happens to this electrostatic work if \((i)\) the charge on the particle and (ii) the mass of the particle is doubled?
