120D 1.0X IUC16. A charge Q is to be divided into two partssuch that the force between them ismaximum. They should be divided as |
|
Answer» let parts are sepereted at a distance of d so repulsion force F= k q(Q-q)/d^2 here Q and d are constant so for maximum force differentiate the force w.r.t q dF/dq = k/d^2[Q -2q] for maximum force dF/dq=0 Q-2q=0 Q/q =2 |
