(a) A physics lab instructor is working on a new demonstration. She attaches two identical iron spheres with mass m = 0.190 g to filaments of length L as shown figure. Both spheres have the same charge of 7.60 nC, and are in static equilibrium when e = 5.20°. What isL (in m)? Assume the filaments are massless. (b) What If? The charge on both spheres is increased until each filament makes an angle of 0 = 10.4° with the vertical. If both spheres have the same electric c what is the charge (in nC) on each sphere in this case? nC

figure.
L.
Both spheres have the same charge of 7.60 nC, and are in static equilibrium when 0 = 5.20°. What isL (in m)? Assume the filaments are massless.
(b) What If? The charge on both spheres is increased until each filament makes an angle of 0 = 10.4° with the vertical. If both spheres have the same electric charge,
what is the charge (in nC) on each sphere in this case?
nC
