Q6 (CAPF/2020) Science & Technology › Basic Science (Physics, Chemistry, Biology) › Basic mechanics concepts Answer Verified

Which one of the following statements with regard to Newton’s third law of motion is not correct?

Force never occurs singly in nature

When the earth pulls a stone downwards due to gravity, the stone exerts a force on the earth

There is a cause-effect relation implied in the third law

There is no cause-effect relation implied in the third law

Result

Your answer: — · Correct: C

Explanation

The correct answer is Option C.

Newton's Third Law describes a mutual interaction where forces occur in pairs. A key conceptual point is that action and reaction forces act simultaneously. There is no time delay between them, and thus no 'cause and effect' relationship where one precedes the other.

Option A is a true statement: Forces never exist in isolation.
Option B is a true statement: The stone and Earth exert equal and opposite forces on each other.
Option D is a true statement: It correctly denies the cause-effect link.

Option C is the incorrect statement (and thus the answer) because it falsely claims a cause-effect relationship exists.
