Two insulating small spheres are rubbed against each other and placed 1 cm apart. If they attract each other with a force of 0.1 N, how many electrons were transferred from one sphere to the other during rubbing?

Two insultating small spheres are rubbed against each other and placed 96 cm apart. If they attract each other with a force of 0.1 N , how many electrons were transferred from one sphere to the other during rubbing ?

(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 ?

Two infinitesimally small bodies are charged by rubbing against each other are found to attract each other with a force of 3.7xx10^(-13) N when separated by a distance of 5xx10^(-8) m. How many electrons were transferred from one body to the other after rubbing ?

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 conducting small spheres are placed with their centers 0.3 m aparts. One is given a charge of 12.0 nC and the other a charge of -18.0 nC . (a) Find the electric force exerted by one sphere on the other? (b) If the spheres are connected by a conducting wire, find the electric force between the two after they attain equilibrium.

Two bodies each of mass 10 kg attract each other with a force of 0.1 milligram weight. What is the distance between them ?

Two small objects are rubbed against each other using insulating handles and then kept at a separation of 1 m from each other in vacuum. Both objects were found to attract each other with a force of 10 N. Assume that the force between the objects is of electrical nature. Calculate the number of electrons that were transferred from one object to another during the rubbing process.
