Question

A satellite is launched into a circular orbit of radius R around the earth. A second satellite is launched into
an orbit of radius 1.01 R. The period of the second satellite is longer than that of then first by approximately:
(A) 0.5% (B) 1.0% (C) 1.5% (D) 3.0%

Answer 1

Answer:

-:Required answer:-

Option C

In the problem, the orbital radius is increased by 1% Time period of satellite, T∝r3/2 Percentage change in time period

=3/2 × (% change in orbital radius )

=3/2× (1%)

=1.5%
