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 larger than that of the first one by approximately

Correct answer

1.5

Step-by-step solution

In the problem orbital radius is increased by 1 % Time period of satellite T ∝ r 3 / 2 ⇒ ∆ T T = 3 2 × ∆ r r Percentage change in the time period = 3 2 [ % change in orbital radius] = 3 2 1 % = 1.5 %
