Two identical metal spheres with +12 muF and -8 muF 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 electrostaticforces between them beforeand after contact is |

Answer» `24:1`  FORCE `F_(1)=-(1)/(4piepsilon_(0))*((12XX10^(-6)xx8xx10^(-6)))/(d^(2))`  `thereforeF_(2)=+(1)/(4piepsilon_(0))*((2XX10^(-6)xx2xx10^(-6)))/(d^(2)` `therefore(F_(1))/(F_(2))=(96)/(4)=(24)/(1)`. |
