Question

a man weight 300 Newton on the surface of the Earth if he were taken to the moon his weight would be 50 new gen calculate the mass of this man on the moon if g is equal to 10 metre per second square​

Answer 1

given

man weights 300 N on earth 50 N on moon

g=10 m/s^2

weight = mass * g

w=m*g

mass on earth

m=w/g

m=300/10

m=30 kg

a very important point to be noted is that mass of an object dosen't depend on the planet it is kept

weight varies from planet to planet because g varies from planet to planet

mass never changes no matter whatever planet it may be it always remain constant

so the mass of the man on moon will be also 30 kg
