Two charged spheres are kept at a finite centre to centre

Last updated: 6/11/2023

Two charged spheres are kept at a finite centre to centre spacing as shown in the figure The force of electrostatic interaction between them is first calculated assuming them point like charges at their respective centres and then force is measured experimentally If the calculated and the measured values are F and Fm respectively which of the following conclusion can you certainly draw A If Fc Fm for like charges and Fc Fm for unlike charges both the spheres must be made of insulating materials B If Fc Fm for like charges and Fc Fm for unlike charges both the spheres must be made of conducting materials C Irrespective of their materials Fc Fm for like charges and Fc Fm for unlike chares D Irrespective of their materials Fc Fm for like charges and F Fm for unlike charges
