Question

In two cases, two identical conducting sphere are given equal charges, in one case of the same type whereas in another case of opposite type. The distance between the spheres is not large comparing with the diameter. Let `F_(1)` and `F_(2)` be the magnitudes of the force of interaction between the spheres, as shown, then

A. `F_(1) gt F_(2)`
B. `F_(1)=F_(2)`
C. `F_(1) lt F_(2)`
D. information is not sufficient to draw the conclusion

Answer 1

Correct Answer - c
In case `I` both are positively charged, due to induction positive charge moves outward on spheres, increasing effective distance between centres of charge causing magnitude of the force to decrease.
