Question

Gravitational force is inversely proportional to the R", then the orbital speed of a satellite of the planet, near planet's surface will be: GM (A) GM GM (n-1) GM VR (B) (C) (D) R1-1 (n-1)RN-1 R-1​

Answer 1

Explanation:

F=

R

n

GmM

=mω

2

R→ω=

R

n+1

GM

hence time period is proportional to R
