Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : A simple pendulum is taken to a planet of mass and radius, $\displaystyle 4$ times and $\displaystyle 2$ times, respectively, than the Earth. The time period of the pendulum remains same on earth and the planet.
Reason (R) : The mass of the pendulum remains unchanged at Earth and the other planet. In the light of the above statements, choose the correct answer from the options given below :
Official answer
From NTA’s final answer key for this paper.
(3)
Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
