Solution

Aim: TO DEMONSTRATE CHARGES ARE OF TWO KINDS:

Procedure:

Take two glass rods A and B and charge each by rubbing them with silk.

Take two Ebonite rods C and D and charge each by rubbing with fur or (flannel) suspend charged rod A by a thread in the stand. Bring charged rod B near A.

A gets deflected (moves away). This show that A is repelled by B.

Now suspend charged rod C in a stand and bring charged rod D near C. Again repulsion is seen.

Now bring charged rod C near the suspended charged rod A. This time attraction is there between the two rods.

This proves that charges are of two kinds A and B have the same kind of r charge called +ve charge and similar charge repels each other whereas rods C and D also have similar charge (negative charge) and repel each other.

Rod A attracts rod C prove that opposite charges attract each other.
