Can someone please help me with this question? Two 5.0 gram conducting spheres are hung side by side from insulating threads. The threads are each 0.4 m long. Both spheres are given the same negative charge. Due to mutual static electric repulsion the spheres now hang with a 40 degree angle between the threads(20 degrees each side of the vertical). a) What is the magnitude of the electric force each sphere experiences? b) What is the charge (in Coloumbs) on each sphere? c) What is the electric field strength experienced by the sphere on the left? Thank-you very much if you can help.
