Two identical conducting spheres carrying different charges attract each other with a force when placed in air medium at a distance 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
View answer and explanation
Correct option: C
Option A is correct because it correctly sets up and solves the equations for the forces before and after contact, leading to the correct ratio of initial charges.
