Two charges, -3.0 μC and 5.0 μC are fixed at a location <1, 1> m and <-0.25, 0 > m, respectively. (a) What is the net electric field at a point p, located at <0, -0.5> m? (b) How much energy is required to bring these two charges to their fixed locations? Is the energy positive or negative? Interpret what the sign of the energy means. (c) If a free proton is now placed at point p, what would be the initial acceleration of the proton? (d) If the proton was released from rest at point p, what would be its speed once its very far away from the two charges?
