A physics lab instructor is working on a new demonstration. She attaches two identical conducting spheres with mass m = 0.190 g to cords of length Las shown in the figure. There are two strings in the figure. The top of each string is connected to the ceiling, and both strings are connected at the same point. The bottom of each string is connected to a spherical mass labeled m. Both strings have length Land hang at an angle of θto the vertical, with the two strings on opposite sides of the vertical. Both spheres have the same charge of 8.00 nC, and are in static equilibrium when θ = 5.45°. What is L (in m)? Assume the cords are massless. m (b) What If? The charge on both spheres is increased until each cord makes an angle of θ = 10.9° with the vertical. If both spheres have the same electric charge, what is the charge (in nC) on each sphere in this case? nC
