Two objects A and B are charged. Let  qA= charge on A and qB= charge on B, then match column I and column II.

When two objects are charged by rubbing them against each other (or charging by friction) they acquired equal and opposite charge.|qA|=|qB|or qA=qBInduced charge may be less than inducing charge in case of dielectric or non-conducting bodiesqA≥qBIf two bodies (say two spheres) of same material and same size are taken, 1st is charge (q=qA) is touched with IInd (initially charged), or charging by conduction, then qB=qA2
