The weight of a body on surface of earth...

The weight of a body on surface of earth is `12.6`N. When it is raised to a height half the radius of earth, its weight will be

A

`2.8`N

B

`5.6`N

C

`12.6`N

D

`25.2`N

Text Solution

Verified by Experts

The correct Answer is:
B
Weight of body on the surface of earth mg `=12.6`N
At height h, the value of g. is given by g.`=g(R^(2))/((R+h)^(2))`
Now `h=R//2`
`:. g.=g((R )/(R+(R//2)))^(2)=(4)/(9)g`
Weight at height `h=(4)/(9)mg=12.6xx(4)/(9)=5.6`N
