Answer VerifiedHint: The surface charge density for a spherical body is defined as the ratio of charge on the surface and the area of the surface. The potential is inversely proportional to the distance of separation of charge and the point where the potential is being measured. Complete answer: Therefore the correct answer is option (C). Note: Here, the point that we are measuring the distance from the centre of the two spheres is very important in determining the potential of the two spheres at a distance d from the centre of the two spheres. If the sphere is made of some charge, then the centre is where the charge is and distance from the centre has to be noted for the calculations. Also it has been assumed here that the spheres are conducting so all the charge resides on the surface.

`"r"_1^2/"r"_2^2` Explanation: ` "Here," sigma_1 = sigma_2` `therefore "q"_1/(4pi_1^2) = "q"_2/(4pi"r"_2^2) Rightarrow "q"_1/"q"_2 = "r"_1^2/"r"_2^2` Concept: Electrical Energy of Two Point Charges and of a Dipole in an Electrostatic Field Is there an error in this question or solution? |
