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 capacitors A and B are charged to the same potential V and are connected in two circuits at t = 0 as shown in figure. The charge of the capacitors at a time t = CR are respectively -

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

A ballong filled with air is weighted so that it barely floats in water as shown in figure. When it is pushed down so that it gets submerged a short distance in water then the balloon

Two identical small equally charged conducting balls are suspended from long threads secured at one point. The charges and masses of the balls are such that they are in equilibrium when the distance between them is a(the length of thread Lgtgta ). Then one of the balls is discharged. what will be the distance b(bltltL) between the balls when equilibrium is restored?

A and B are two concentric spherical shells. If A is given a charge +q while B is earthed as shown in figure then
