Bus L as 92 Two small identically charged conducting spheres 1and 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=(3.6*10^-8) , the length of the thread is L=160cm and the horizontal separation is x=13cm. 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=(4.5*10^-9)C. Find the separation after the system reaches equilibrium from this step. Hint: Use small angle approximation and if you use that then h-L You may not be able to answer (a),(b) before you find (c), but finding expression for (a),(b) are necessary in order to find (c). a) Find the magnitude of electric force on q1 due to q2 b) Find the magnitude of electric force on q1 due to 13? c) Find the separation after the system reaches equilibrium
