The FARE has how many suction hoses and how many grounding rods?

A. 1 suction hose and 1 grounding rod
B. 2 suction hoses and 2 grounding rods
C. 3 suction hoses and 3 grounding rods
D. 4 suction hoses and 4 grounding rods

Answer :

Final answer:

Correct option is b.This answer explains how charges distribute on metal balls when subjected to an external negative charge, their interaction with grounding, and the phenomenon of induction in physics.

Explanation:

a. If the two balls are in contact with each other, they will both have an equal amount of charge.

b. The balls get these charges through the process of induction, wherein the negative rod polarizes the charges in the balls causing them to have the same charge.

c. When the second ball is momentarily grounded, the charge redistributes in the system, and the second ball will lose its charge because the excess charge flows to the ground.

therefore Correct option of answer is b.
