When two bodies A and B are rubbed, they acquire charge by friction, If the charge on A is negative, then the charge on B is "_______" .

An object A acquires positive charge 9.6muC , when rubbed against another object B. Is there any change is mass of object B ? Will this increase or decrease the mass of B and how much ?

What is the correct order of following steps for an experiment to prove that like charges repel each other? (A) Take two galss rods. (B) Now bring these two charged rods nearer. (B) Now bring these two charged rods nearer. (C) Charge them by rubbing each glass rod with a silk cloth. (D) The glass rods equal other showing that like charges repel each other.

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 C, then A becomes negatively charged, What will happen if an object made of substance B is rubbed against an object made of substance C? (a) B becomes positively charged and C becomes positively (b) B becomes positively charged and C becomes negatively charged. (c ) B becones negatively charged and C becomes positively charged. (d) B becomes negatively charged and C becomes negatively charged.
