Gravitation question

2022 · 27 Jul · Shift 2 · Q46

JEE MainPhysicsGravitationMCQ+4 / −1
A body of mass m\mathrm{m}m is projected with velocity λ ve\lambda \,v_{\mathrm{e}}λve​ in vertically upward direction from the surface of the earth into space. It is given that vev_{\mathrm{e}}ve​ is escape velocity and$$\lambda(R : radius of earth)
  1. A
    R1+λ2\frac{\mathrm{R}}{1+\lambda^{2}}1+λ2R​
  2. B
    R1−λ2\frac{R}{1-\lambda^{2}}1−λ2R​
  3. C
    R1−λ\frac{R}{1-\lambda}1−λR​
  4. D
    λ2R1−λ2\frac{\lambda^{2} \mathrm{R}}{1-\lambda^{2}}1−λ2λ2R​
