Two small conducting spheres of radius R and 2R have charges 40 μ C and -10 μ C respectively, placed at a dis†an ce r from each other experience a force of magnitude F_1. If they are brought in contact and separated by same dis†an ce r, they experience force of magnitude F_2. The ratio of F_1 to F_2 is (r>>R) (1) 1:1 (2) 2:1 (3) 4:3 (4) 3:4 |
