The escape velocity of an object from the Earth depends upon the mass of the Earth $(M)$,its mean density $(\rho)$,its radius $(R)$,and the gravitational constant $(G)$. Thus,the formula for escape velocity is:

  • A
    $v = R\sqrt{\frac{8\pi}{3}G\rho}$
  • B
    $v = M\sqrt{\frac{8\pi}{3}GR}$
  • C
    $v = \sqrt{2GMR}$
  • D
    $v = \sqrt{\frac{2GM}{R^2}}$
