Question

Please select all that apply!
A silk cloth gains electrons when rubbed over a glass rod. A different glass rod gains electrons when rubbed with rabbit fur. What will happen if the two charged glass rods approach one another and why?

A:The rods will repel each other because they have unlike charges.
B:There will be no reaction between the rods.
C:The rods will attract each other because they are both positively charged.
D:The rods will attract each other because they have unlike charges.
E:The rods will repel each other because they have like charges.

Answer 1

C The rods will attract each other because they are both positively charged.

Answer 2

Answer:

The correct answer is statement D.

Explanation:

The opposite charges attract each other and the charges that are identical repel each other. It is mentioned that a cloth made up of silk acquires electrons when scrubbed over a glass rod, which signifies that a glass rod lost electrons, and thus becoming positively charged. On the other hand, a different glass rod acquires electrons when it is rubbed with rabbit fur, thus, glass rod acquiring a negative charge. Hence, it can be said that the two different rods will attract each other, as they possess, unlike charges.
