Question

a satellite is put in a circular orbit of radius r. another satellite is thrown in a circular orbit of radius 1.01r

Answer 1

Answer:

Kepler's 3rd law, T

2

∝R

3

⟹T=kR

2

3

where k is a constant

T

ΔT

=

2

3

R

ΔR

Now, ΔR=.01R ⟹

T

ΔT

=0.015

Thus, percentage change

T

ΔT

×100=1.5 increased
