Answer 1

Answer:

Given:

A simple pendulum has been taken to the top of the mountain.

To explain:

If it will lose or gain time ?

Explanation:

Time period of a simple pendulum is given by the following formula:

$T = 2\pi \sqrt{ \frac{l}{g} }$

, where l => length of string and g is gravity.

Now let's assume that the mountain is extremely high.

In that case, the gravitational force /gravitational acceleration will be decreased considerably.

Decrease in gravity will follow the Equation:

$g" \: = g(1 - \frac{2h}{R} )$

where h => height above earth surface and R is the radius of the Earth.

Hence the value of "g" will decrease .

As a result, the Time period will increase. And the pendulum will gain time.

Answer 2

Explanation:

A pendulum clock gain time when taken to the top of a mountain.
