In an electric field, the lines on the left have twice the separation as those on the right. (a) If the magnitude of the field at A (particle in the field with lesser separated lines) is 58 N/C, what is the magnitude of the force on a proton at A? (b) What is the magnitude of the field at B (particle in the field with the larger separated lines)?
