A satellite is launched into a circular orbit of radius ' R ' around the earth. A second satellite is launched into an orbit of radius 1.03 R . The time period of revolution of the second satellite is larger than the first one approximately by

Options

  1. A9 %
  2. B3 %
  3. C4.5 %
  4. D2.5 %

Correct answer

C. 4.5 %

Step-by-step solution

T₁ (R)^ 3 / 2 and T₂ (1.03 R)^ 3 / 2 T₂=(1.03 R)^ 3 / 2 T₁ 1.045 T₁ So T₂ will larger by 4.5 % w.r.t. T₁ .
