ELECTROSTATICS - Topic Wise Multiple Choice Questions (MCQ)
Electrostatics is a branch of physics that studies electric charges at rest. Since classical physics, it has been known that some materials such as amber attract lightweight particles after rubbing.

8 )
Two small conducting sphere of equal radius have charges + 1 c and – 2c respectively and placed at a distance d from each other experience force F1. If they are brought in contact and separated to the same distance, they experience force F2. The ratio of F1 to F2 is …………
9 )
Two small charged spheres repel each other with a force 2 × 10–3 N. The charge on one sphere is twice that of the other. When these two spheres displaced 10 cm further apart the force is 5 × 10–4 N, then the charges on both the spheres are…….
