1.	A certain charge Q is divided at first into two parts,(q) and (Q-q). Later on the charges are placed at acertain distance. If the force of interaction betweenthe two charges is maximum then-
Answer» let parts are sepereted at a distance of d so repulsion force F= k q(Q-q)/d2 here Q and d are constant so for maximum force differentiate the force w.r.t q dF/dq = k/d2[Q -2q] for maximum force dF/dq=0 Q-2q=0 Q/q =2

A certain charge Q is divided at first into two parts,(q) and (Q-q). Later on the charges are placed at acertain distance. If the force of interaction betweenthe two charges is maximum then-

Answer»

let parts are sepereted at a distance of d

so repulsion force F= k q(Q-q)/d2

here Q and d are constant so for maximum force differentiate the force w.r.t q

dF/dq = k/d2[Q -2q]

for maximum force dF/dq=0

Q-2q=0

Q/q =2
