Question

When a clock controlled by a pendulum is taken from the plains to a mountain, it becomes slow but a wrist-watch controlled by a spring remains unaffected. Explain the reason for the difference in the behaviour of the two watches.

Answer 1

When a clock controlled by a pendulum is taken from the plains to a mountain, it becomes slow but a wrist-watch controlled by a spring remains unaffected Due to decrease in the value of g at the mountain, the time period of the pendulum of the clock increases. On the other hand, the spring watch remains unaffected by the variation in g.

Answer 2

Answer:

Due to the decrease in the value of (g )at the mountain,the time period of the pendulum of the clock increases on the other hand the, the spring watch remains unaffected by the variation of (g).
