Question

the mass of a student of classX on the earth is 48kg . the mass of this student on Moon's surface is:​

Answer 1

Hey

Mass is constant both on Earth and Moon but there is a variation in the gravitational field. Gravitational force expressed on Moon is 1/6 of that on Earth.

Gravitational force on Earth:

F=mg=48×9.8=470.4N

Now gravitational force on moon:

$\frac{1}{6} \: of \: that \: on \: earth$

=1/6×470.4=78.4N
