In the figure the electric field lines on the left have twice the separation as those on the right. (a) If the magnitude of the field at A is 57 N/C, what is the magnitude of the force on a proton at A? (b) What is the magnitude of the field at B? (a) Number i (b) Number Units Units B N N/C or V/m In the figure the electric field lines on the left have twice the separation as those on the right.
