Question

2. A negativity charged metal sphere
is fixed to a wooden stand. What will
happen to its charge it
(a) touched by a neutral glass rod
(b) touched by a metal rod​

Answer 1

Answer:

A neutral metal sphere is touched by a negatively charged metal rod. ... During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively.

Explanation:

Answer 2

When negatively charged metal sphere

is fixed to a wooden stand and is touched by any neutral glass rod or my metal rod, then the following things may happen:-

a). When touched by a neutral glass rod.

• When a negatively charged metal sphere is touched by a neutral glass rod the. no other charge is induced in it.
• This happens because the net charge on the metal sphere remains conserved.

b). When touched by a metal rod.

• When a negatively charged metal sphere is touched by a metal rod, the charges are induced on the rod as well as on the metal sphere.
• Both the rod and the metal sphere will try to acquire equal and opposite charges.
• To attain the same potential, some positive charges flow from the rod to the metal sphere to have equal negative charges.
• And thus, the total charge of the system remains conserved.
