Vedclass · Accepted Answer

When they carry charges of the same sign $F_c > F_m$ and when they carry charges of opposite signs $F_c < F_m$ only when they are conductors.

Vedclass · Answer

(B) When two charged spheres are placed near each other,the charge distribution on their surfaces is affected by the electrostatic interaction (induction in conductors or polarization in insulators).If the spheres have charges of the same sign,the charges on the surfaces redistribute such that they move further apart from each other. This increases the effective distance between the centers of charge,resulting in a measured force $F_m$ that is less than the calculated force $F_c$ (assuming point charges at the centers). Thus,$F_c > F_m$.If the spheres have charges of opposite signs,the charges on the surfaces redistribute such that they move closer to each other. This decreases the effective distance between the centers of charge,resulting in a measured force $F_m$ that is greater than the calculated force $F_c$. Thus,$F_c This phenomenon occurs for both conductors and insulators due to the redistribution of charge,making the correct option $B$.
