Question

a man weighs 600 N at earth surface at what height above the Earth's surface is weight will become 300 N?(Radius of earth=6400 km​

Answer 1

Answer:The height above the surface of the earth is 2649.6 km.

Explanation:

Given that,

Radius of earth R = 6400 km

Weight of the man at earth mg = 600N

Weight of the man at height above the earth's surface mg'=300N

We know that,

The gravity at the surface of the earth is.....(I)

The gravity at the height above the earth's surface.....(II)

Divided equation (I) by equation (II)

Put the value of g and g' in equation (III)

Hence, The height above the surface of the earth is 2649.6 km.
