Gravitation question

2024 · 1 Feb · Shift 2 · Q72

JEE MainPhysicsGravitationMCQ+4 / −1
A light planet is revolving around a massive star in a circular orbit of radius R\mathrm{R}R with a period of revolution T. If the force of attraction between planet and star is proportional to R−3/2\mathrm{R}^{-3 / 2}R−3/2 then choose the correct option :
  1. A
    T2∝R7/2\mathrm{T}^2 \propto \mathrm{R}^{7 / 2}T2∝R7/2
  2. B
    T2∝R3\mathrm{T}^2 \propto \mathrm{R}^3T2∝R3
  3. C
    T2∝R5/2\mathrm{T}^2 \propto \mathrm{R}^{5 / 2}T2∝R5/2
  4. D
    T2∝R3/2\mathrm{T}^2 \propto \mathrm{R}^{3 / 2}T2∝R3/2
