A system of three charges is shown, two electrons (A and B) and a positively charged atomic mucleus Containing two protons (C) (you can think of this as sort of approximating a specific configuration of an atom). B d= 1010 m A (2p) C d= 1010 m a) Write the position vector from B to A FBA and that from C to A fCA. b) Calculate the electric force FA acting on charge A by caleulating the force FBA and Fea. Give your answer in unit vector notation. c) What is the acceleration of charge A, assuming no other forces act on it?
