  • The mass of a planet is six times that of the earth. The radius of the planet is twice that of the earth. It's the escape velocity from the earth is v , then the escape velocity from the planet is:

    A
    `sqrt(3)v`
    B
    `sqrt(2)v`
    C
    `sqrt(5)v`
    D
    `sqrt(12)v`
  • A body is imparted a velocity v from the surface of the earth. If v_(0) is orbital velocity and v_(e) be the escape velocity then for :

    A
    `v = v_(0)` the body follows a circular track around the earth.
    B
    `v gt v_(0)`, but `lt v_(e)`, the body follows elliptical path around the earth
    C
    `v lt v_(0)`, the body follows elliptical path and returns to surface of earth
    D
    `v gt v_(e)`, the body follows hyperbolic path and escapes the gravitational pull of the earth
