Q- Two equally charged point mass of mass m each are suspended from a point by massless threads of length L. In equilibrium position each thread makes and angle ɵ with vertical.
(a) Find the ratio of magnitudes of horizontal electric force and vertical gravitational force on a the masses.
(b) What is the ratio if the angle ɵ = 150 ?
(C) If each mass is 0.15 gm and the length L =14 inch, what is the magnitude of excess charge on each mass?
