Two identical metal spheres charged with +12muCand-8muC are kept at certain distance in air . They are brought into contact and then kept at the same distance . The ratio of the magnitudes of electrostatic forces between them before and after contact is |
Answer» Solution :Bofore contact `thereforeF_(2)=+(1)/(4piepsilon_(0))*((2xx10^(-6)xx2xx10^(-6)))/(d^(2))THEREFORE(F_(1))/(F_(2))=(96)/(4)=(24)/(1)` |
