Two equal masses separated by a distance `d` attract each other with a force (`F`). If one unit of mass is transferred from one of them to the other, the force

Two identical charged spheres separated by a distance repel other with a force F. If 10% of electrons are transferred from one sphere of the other ,then the force between them becomes

Two body of same mass 'm' each are placed at distance d from each other, then gravitational force between them is F. If 50% mass is transferred from one body to another and distance between them increased by 50% then new gravitational force between them will be :

(a) Two protons are placed at some separation in vacuum. Find the ratio of electric and gravitational force acting between them. (b) Two point charges are placed at separation 3 m in vacuum. What can be the minimum force between them. (c ) A charge Q is to be divided on two objects. What should be the value of the charges in the objects so that the force between them is maximum ? (d) Two insulating small spheres are rubbed against each other and placed 1.6 cm apart. If they attract each other with a force of 0.9 N , how many electrons were transferred from one sphere to the other during rubbing ?
