The centres of two identical small conducting spheres are 1m apart. They carry charge of opposite kind and attract each other with a force F. When they are connected by a conducting thin wire they repel each other with a force `F//3`. What is the ratio of magnitude of charge carried by the sphere initially ?

The centres of two identical small conducting sphere are 1 m apart. They carry charge of opposite kind and attract each other with a force F. when they connected by conducting thin wire they repel each other with a force F//3 . The ratio of magnitude of charges carried by the spheres initially in n : 1 . Find value of n

Two small equal spheres carrying unlike and unequal charges are placed 8 cm apart and attack each othwer with a force of 4xx10^(-5) N. After they have been connected for a moment by a thin conducting wire, they repel each other with a force of 2xx10^(-5) N. Calculate their original charges.

Two conducting spheres of radii 5 cm and 10 cm are given a charge of 15mu F each. After the two spheres are joined by a conducting wire, the charge on the smaller sphere is

Two charged spheres attract each other with a force. If they are touched with each other and thereafter brought back to their initial positions, the two spheres

Two balls carrying charges of +3muC and -3 muC attract each other with a force F. If charge +3muC is added to both, the force between the balls will be :

Two identical conducting sphere carrying different charges attact each other with a force F when placed in air medium at a distance d apart. The spheres are brought into contact and then taken to their original positions. Now, the two sphere repel each other with a force whole magnitude is equal to the initial attractive force. The ratio between initial charges on the spheres is

Two identical conducting sphere carrying different charges attact each other with a force F when placed in air medium at a distance d apart. The spheres are brought into contact and then taken to their original positions. Now, the two sphere repel each other with a force whole magnitude is equal to the initial attractive force. The ratio between initial charges on the spheres is

Two small identical spheres having charges +10 muC and - 90muC attract each other with a force of F newton . If they are kept in contant and then separated by the same distance, the new force between them is -
