When an object gets negatively charged by the process of friction, then:
(a) the object loses some electrons (b) the object loses some protons
(c) the object gains some electrons (d) the object gains some protons
If an object made of substance A is rubbed with an object made of substance B, then A becomes positively charged and B becomes negatively charged. If, however, an object made of substance A is rubbed against an object made of substance C, then A become negatively charged. What will happen if an object made of substance B is rubbed against an object made of substance C?
If an object object contains n1 proton and n2 ectrons,the net charge on the object is??
If an object gains an electron it will become negatively charged and object which looses an electron, it will become positively charged. When they do not come in contact, charge will remain them as it is but they can take or loose charges from the objects.
But when we rub comb from our hair, it attracts bits of paper. After some time the charge is gone . How?
