Question

Match the following;1.escape velocity,2.Gravitation acceleration,3.Gravitational forces​

Answer 1

→Part B

Atmosphere exists when the air molecules can't escape the

planets gravitational force.

Hence, existence of atmosphere on a planet also depends upon the

escape velocity of the planet, but is independent of the mass of the planet.

And the temperature of the planet.

And existence of atmosphere has no reference with mass of body or mass of body, so we have nothing to do with these options.

Hence B→2,4,5
