Two spheres A and B of radius 4 cm and 6 cm are given charges of `80 muC and 40 muC`, respectively. If they are connected by a fine wire, then the amount of charge flowing from one to the other is

Two metallic sphere of radii 1 cm and 3 cm are given charges of 4xx10^(-2)C and respectively. If these are connected by a counducting wire, the final charge on the bigger sphere is

Two spheres of radii 3cm and 8cm are charged with 4xx10^(-9)C and 1.6xx10^(-9)C of electricity respectively. If they are joined by a wire, how much charge will flow from one to the other sphere?

Figure shows two conducting spheres separated by large distance and of radius 2 cm and 3 cm containing charges 10 muC and 20 muC respectively. When the spheres are connected by a conducting wire then find out following : (i) Ratio of the final charge. (ii) Final charge on each sphere. (iii) Ratio of final charge densities. (iv) Heat produced during the process.

Two spheres of radii 2 cm and 8 cm are charged equally with an amount of 10^(-10)C . If they are connected by a thin copper wire, what amount of charge will flow through this wire.

80 microC charge is given on sphere of 4 cm radius and 40 muC charge is given on sphere of 6 cm radius. If they are connected by a conducting wire, then charge transferred from sphere of 4 cm radius to sphere of 6 cm radius will be......

The two spherical shells are at large separation, one of them has radius 10 cm and 1.25 muC charge. The other is of 20cm radius and has 0.75 muC charge. If they are connected by a conducting wire of negligible capacitance, the final charge on the shells are :
