Question

17. As a body moves to a place 1600 km above the surface of a planet then the value of
acceleration due to gravity of that planet reduces to 9/16 of its value at the surface of
that planet, Calculate the radius of planet.
Plz no spamming​

Answer 1

Answer:

Given :  d=1600km     R=6400km

Acceleration due to gravity at a depth d, g  

d  =g  

s

​  

(1−  

R

d

​  

)

where g  

s

​  

=9.8ms  

−2

 is acceleration due to gravity at earth's surface.  

∴  g  

d

​  

=9.8(1−  

6400

1600

​  

)=7.35ms  

−2
