Question

A spring-mass clock gives correct time at equator. Will it gain times or lose time as it is taken to
poles? Can a spring-mass clock be used in a Earth satellites?​

Answer 1

Explanation:

time period of the loaded spring is independent of the acceleration due to gravity g......so if you take it to the polls are equator you will not gain or loss the time..... yes u can..

Answer 2

Given:

A spring-mass clock gives correct time at equator.

To find:

• If the clock will gain or lose time when taken to poles .
• If the clock can be used in satellites.

Concept:

Any spring mass system can be used as a clock. Let the mass be m , spring constant be k , then it's time period be T.

$\boxed{ \sf{T = 2\pi \sqrt{ \dfrac{m}{k} } }}$

The main differences between the pole and the equator of the Earth is that the gravitational acceleration is is a little higher in poles as compared to the equator.

However , the clock won't lose/gain any time because its time period is not dependent on any gravity factor.

In the satellites , the gravitational acceleration acting on any body is zero . But still , the clock can be used in the satellites because the time period doesn't depend on gravity.

On a different note, a simple pendulum will have variations in time period whenever taken from equator to pole. Also , it can't be used in a satellite.

The reason is the dependence of its Time period on gravity.
