Question

find the weight of a stone on the surface of the earth if its mass is 20 kg. (g=9.8 m/s square)find the weight of a stone on the surface of the earth if its mass is 20 kg. (g=9.8 m/s square)​

Answer 1

Answer:

ANSWER

As we know a body's weight is the product of its mass and acceleration acting on it i.e

W=ma

given, m=20kg

here acceleration (a) would be g=10m/s²

{because on Earth a body experiences acceleration and due to gravity (g)}

so, weight of the body on Earth is

W=20×10=200kg

as we know,

weight on moon=

6

1

weight on earth

so weight on moon=

6

200

=33.33kg
