step 1: Two small identically charged conducting spheres 1 and 2 of equal mass are hung from fixed support with non-conducting threads of equal length as shown in the figure. Both the spheres have equal mass m1=m2=m and equal charge q1=q2=q. Assume that the charge of each sphere is q=36nC, the length of the thread is L=219cm and the horizontal separation is x=11cm. a) Find out the mass of each sphere. step 2: Now, say we discharge sphere 2, without changing any other variables. Discharging means that the new charge of sphere 2 is q′2=0. Explain what will happen and answer the followings: b) What will be the new charge of the spheres after they reach equilibrium from step 2. c) What will be the new separation of the spheres after they reach equilibrium from step 2. Hint: Use small-angle approximation.
