Question

Find the weight of a stone on the surface of earth if its mass is 20kg (g=9.8m/s2)

Answer 1

like if it helps you

Explanation:

as weight = mass × gravity ( of the given planet )

so,

mass = 20kg

gravity = 9.8 m/s^2

weight = 20 × 9.8

therefore , weight = 196 N

Answer 2

Answer:

W =196J

Explanation:

Mass m =20kg

g =9.8m/s^2

Weight of the stone,

W = mg = 20*9.8

= 196kgm/s^2=196J
