Gravitation Question 31
Question: Radius of earth is around 6000 km. The weight of body at height of 6000 km from earth surface becomes [RPMT 1997]
Options:
A) Half
B) One-fourth
C) One third
D) No change
Show Answer
Answer:
Correct Answer: B
Solution:
$ [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.
