You find your mass to be 42 kg on a weighing machine. Is your mass more or less than 42 kg?

SOMETHING YOU SHOULD KNOW FIRST

A weighing machine measures the weight of a body

When we stand on a weighing machine, our weight acts downwards while upthrust due to air acts upwards.

So, due to upthrust , the body appears to loose some weight.

As a result, our apparent weight becomes less than the true weight.

║⊕ANSWER⊕║

The weighing machine measures this apparent weight and hence the mass indicated by it is less than the actual mass.

Our actual mass will be more than 42 kg.

Earth has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m, while saturn has a mass of 5.68 x 1026 kg and a radius of 6.03 x 107 m. find the weight of a 65.0 kg person at the following locations? a) on the surface of the earth. b) 1000 km above the surface of earth. c) on the surface of saturn. d) 1000 km above the surface of saturn.
