Question
Choose the correct statement:
Assertion: Centripetal and centrifugal forces get nullified
Reason: They are always equal and opposite.
- The assertion is correct, and the reason is incorrect
- The assertion and the reason are correct; the reason is a correct explanation for the assertion.
- The assertion is correct, the reason is correct; the reason is not a correct explanation for the assertion.
- The assertion is incorrect, and the reason is correct.
Hint:
Centripetal force acts on the body in circular motion but centrifugal force does not act on this body.
The correct answer is: The assertion is incorrect, and the reason is correct.
Centripetal force is a real force whereas Centrifugal force is a pseudo force. The force that keeps an object moving with a uniform speed along a circular path is the Centripetal force and the force used in non-inertial frame of reference to explain the apparent outward force experienced by the object moving in circular motion is the Centrifugal force.
So, these two forces, despite being opposite in direction, do not cancel out each other. So, the Assertion is False.
The magnitude of both these forces is same but their direction is opposite. So, the Reason is True.
