Solution

The correct option is B $M_{m} = M_{e}$
Mass of a body is constant that neither depends on the location of the body nor on the gravitational force exerted on the body.
So mass of the body will remain unchanged on moon i.e. $M_{m} = M_{e}$

Hence, correct answer is option $B .$

Q. The minimum speed with which a body is projected from the surface of the earth so that it reaches to the surface of the moon is v while the minimum speed with which a body is projected from the surface of the moon so that it reaches to the surface of the earth is v'. Then, disregarding the spinning and orbital motions of the earth and the moon, and using the fact that

\frac{M_{E}}{R_{E}} > \frac{M_{M}}{R_{M}}

where

M_{E}, M_{M}, R_{E}

and

R_{M}

are mass of earth, mass of moon, radius of earth and radius of the moon respectively, we can say that :

The ratio of acceleration due to gravity on the earth to the moon is : (Take Mass of the earth $= M_{e}$ , the radius of earth $= R_{e}$ , Mass of the moon $= M_{m}$ and the radius of moon $= R_{m}$ )

If mass of a body on the moon be denoted by Mm and on the earth be denoted by Me, then

The correct option is B Mm=MeMass of a body is constant that neither depends on the location of the body nor on the gravitational force exerted on the body.So mass of the body will remain unchanged on moon i.e. Mm=MeHence, correct answer is option B.
