Question
Give scientific reason:
A charge can be obtained on a rubbed ebonite rod held in the hand but not on a rubbed metal rod held in the hand.
Solution
The rubbed ebonite rod contains more electrons so it acquires the negative charge so a charge is acquired by it. But, in the rubbed metal rod, electrons are transferred but through hands and body, they pass to the earth so no charges will be there while the metal rod is held in hand.
