Question

If a man had about 14 kg on the moon. What would be his weight on Earth? (Consider gravity on Earth equal to 10 m / s2).

Answer 1

the gravitational force in moon is 6 times less than compared to earth so 14×6=84kg (by my calculation

Answer 2

Hello Dear
we know that weight is defined as force acting on a body due to gravity.
and is given by
W = m × g
where m = mass of body
g = acceleration due to gravity.= 10m/s²(given)


And we know that gravity on moon is 1/6th to that of Earth's
so acceleration due to gravity on moon will be 10/6 m /s²


so

W = m × g. --------1
weight given on moon is 14Kg
so
14 = m × 10/6
mass = 14/10/6
=>. mass = 14×6/10


so now on Earth weight will be
here take mass = 14×6/10

so W = 14×6/10. × 10
=> w = 84. Kg.
