(a) Give the signs of the potential difference V_P - V_Q; V_B - V_A. (b) Give the sign of the potential energy difference of a small negative charge between the points Q and P; A and B. (c) Give the sign of the work done by the field in moving a small positive charge from Q to P. (d) Give the sign of the work done by the external agency in moving a small negative charge from B to A. (e) Does the kinetic energy of a small negative charge increase or decrease in going from B to A?
Understand the Problem
The question consists of multiple parts asking about potential difference, potential energy difference, work done by the field, and kinetic energy changes related to electric charges. It requires an understanding of electrostatics principles, specifically how charges interact and how potential and energy are calculated in electric fields.
