(d) Mass of the particle Two identical conducting spheres carrying different charges attract 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 spheres repel each other with a force whose magnitude is equal to that of the initial attractive force. The ratio between initial charges on the spheres is Karala PET 2008] (a) –(3+78) only (b) - 3+ 18 only (c) (3 + √8) or (-3+/8 (d) + 13 (e) - 18

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 identical conducting spheres, fixed in space, attract each other with an electrostatic force of 0.108 N when separated by 50.0 cm , centre-to-centre. A thin conducting wire then connects the spheres. When the wire is removed, the spheres repel each other with an electrostatic force of 0.0360 N . What were the initial charges on the spheres?
