step 1: Two small identically charged conducting spheres 1 and 2 of equal mass are hung from a 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=24nC , the length of the thread is L=227cm and the horizontal separation is x=14cm. 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 the sphere 2 is q′2=0. Explain what will happen in your script 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.

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 the sphere 2 is q′2=0. Explain what will happen in your script 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.
step 3: Now say we insert another charged sphere 3 in between with a thread of length h which is shown in figure 2. Note that, value of h is the vertical distance from sphere 1 and 2 to the ceiling. Assume that the charge of sphere 3 is q3=3.0nC. Find the separation after the system reaches equilibrium from this step.
