The figure below shows a small, charged bead, with a charge of q = +39.0 nC, that moves a distance of d = 0.166 m from point A to point B in the presence of a uniform electric field E of magnitude 270 N/C, pointing right. + (a) What is the magnitude (in N) and direction of the electric force on the bead? magnitude N direction ---Select--- (b) What is the work (in ]) done on the bead by the electric force as it moves from A to B? (c) What is the change of the electric potential energy (in J) as the bead moves from A to B? (The system consists of the bead and all its surroundings.) PEB - PEA = (d) What is the potential difference (in V) between A and B? VB - VA
