Question:

Radius of earth is around 6000 km. The weight of body at height of 6000 km from earth surface becomes :

Options:

Half

One-Fourth

One-third

No change

Correct Answer:

One-Fourth

Explanation:

\(g'=g{{\left( \frac{R}{R+h} \right)}^{2}}\)

Þ when h=R then : \(g'=\frac{g}{4}\)

So the weight of the body at this height will become one-fourth.
