In the given figure two tiny conducting balls of identical mass `m` and identical charge `q` hang from non-conducting threads of equal length `L`. Assume that `theta` is so small that than `theta~~ sin theta`, then for equilibrium `x` is equal to

Two idential pith balls. Each of mass 'm' and charges 'q' hang from noncoducting threads of length I as shown in figure , theta is very small and hence tan theta ~~sin theta . Show that , for equilibrium x=[( q^(2) l)/( 2pi in _0mg) ]^((1)/(3))

Two small conductiong ball of identical mass 20 g and identical charge 10^(-10) C hang from non-conducting threads of length, L = 300 cm. If the equilibrium separation of balls is x and x lt lt L then the magnitude of x is (Assume, 4pi in_(0) =1/(9xx10^(9)) F/m and g=10 m//s^(2) )
