Two very small conducting spheres, each of mass 1.0x10 kg are suspended at a common point by very thin (weightless') non-conducting threads of length 0.2 m. a charge +q is placed on each sphere. suspending threads make an angle of 10. assume g-9.8 m/s2 and negligible mass for the threads. a) draw labelled force diagrams for the system b) calculate the value for q
