2 One end of an insulating rigid rod of negligible mass and length pivoted to a fixed point O A small ball of mass m having a negat charge of modulus q is attached to the lower end of the rod Anot small ball carrying a positive charge Q is fixed at a height h above point O as shown in the figure What should the range of values of m m of the lower ball be so that the rod remains in a state of sta Qqh equilibrium Acceleration due to gravity is g my 47 E 9 h l
