Question

pole is 1/2 submergedin mud, 1/3
in water and
10 dm in air find the total length​

Answer 1

Answer:

The distance from the poles to the centre of the earth is lesser than the distance from the equator to the centre of the earth. Therefore the acceleration due to gravity is greater at the poles than at the equator.

Answer 2

Step-by-step explanation:

Let the total length be ‘L'.

The length in air is L-(L/2 + L/3).

This gives us the length in air is L/6.

But it is given that length in air is 20 dm

So 20 dm= L/6

Therefore L is 120 dm. That is 12 metres.
