Two identical helium filled balloons A and B fastened to a weight of 5 g by threads floats in equilibrium as shown in figure. Calculate the charge on each balloons, assuming that they carry equal charge.

Two identical He-filled spherical balloons each carrying a charge q are tied to a weight W with strings and float in equlibrium, as shown in figure. (i) Find the magnitude of q, assuming that the charge on each balloon acts as if it were concentrated at the center. (ii) Find the volume of each balloon. Take the density of He as rho_(He) and the density of air as rho_(a) . Ignore the weight of the unfilled balloons . ,

Two identical small charged spheres, each having a mass m, hang in equilibrium as shown in fig. the ligth of each string is l, and the angle made by any string with the vertical is theta . Find the magnitude of the charge on each sphere.

Two similar balloons filled with helium gas are tied to L m long string. A body of mass m is tied to another ends of the strings. The balloons float on air at distance r . If the amount of charge on the ballons is same then the magnitude of charge on each balloon will be
