A simple second pendulum is mounted in a rocket. Its time period will decrease when the rocket is
1 moving up with uniform velocity
2 moving up with uniform acceleration
3 moving down with uniform acceleration
4 moving around the earth in geostationary orbit
Explanation:
The time period of simple pendulum is will decrease, when increases and will increase when rocket moves up with a uniform acceleration.

Assertion : The value of acceleration due to gravity is low at the mountain top than at the plane. Reason : If a pendulum clock is taken to mountain top, it will gain time.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
The value of acceleration due to gravity is lower at the mountain top due to the increased distance from the Earth's center, causing the clock to loose time. So, correct option is (3).

4 Cannot be predicted
Explanation:
Time period of simple pendulum placed in a van accelerating at the rate of a is given by However, the time period of mass attached to the spring is It is independent of as well as . Hence, when the van accelerates, the time period of the simple pendulum decreases and that of spring remains unchanged. Hence, and i.e.
