each equal to q
Two charges, each equal to q, are kept at x=−a and x=a on the x-axis. A particle of mass m and charge q0=q/2 is placed at the origin. If charge q0 is given a small displacement (y is much less then a) along the y-axis, the net force acting on the particle is proportional to

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 ρHe and the density of air as ρa . Ignore the weight of the unfilled balloons .
