A glass rod, when rubbed with silk cloth, acuires a charge 1.6 xx 10^-13 coulomb. What is charge on the silk cloth?

Frictional electricity The electricity developed in bodies when they are rubbed with each other is called frictional electricity. There are two kinds of charges, namely positive and negative. Like charges repel each other and unlike charges attract each other. when a glass rod is rubbed with silk cloth, glass rod becomes positively charged are silk acquires the same amount of negative charge. the concept of positive and negatice charges was introduced by Benjamin Franklin. The charge is always quantised and conserved in a system. The number of electrons for one coulomb of charge is
