Escape velocity of a body on the surface of earth is independent of

Question

Escape velocity of a body on the surface of earth is independent of (A) mass (B) radius of earth (C) direction of projection of body (D) Both (a) and (c)

Tardigrade Admin · Accepted Answer

Escape velocity on the surface of earth is given by

v = 2 g R_{e}

i.e.

v \propto R_{e}

Hence, escape velocity does not depend on the mass and direction of projection of body, it depends on the radius of earth.
Hence, options (a) and (c) are correct.

Q. Escape velocity of a body on the surface of earth is independent of

mass

radius of earth

direction of projection of body

Both (a) and (c)

Escape velocity on the surface of earth is given by v=2gRe​​ i.e. v∝Re​​ Hence, escape velocity does not depend on the mass and direction of projection of body, it depends on the radius of earth. Hence, options (a) and (c) are correct.

Escape velocity on the surface of earth is given by
$v = 2 g R_{e}$
i.e. $v \propto R_{e}$
Hence, escape velocity does not depend on the mass and direction of projection of body, it depends on the radius of earth.
Hence, options (a) and (c) are correct.
