Question

a body of mass 10kg is taken from the earth to the moon, if the value of g on earth is 9.8m/s2 and on moon is 1.6m/s2, find weight of the body on earth, weight of body on moon?

Answer 1

Given

• Mass of the earth (m) = 10kg
• gₑₐᵣₜₕ = 9.8m/s²
• gₘ₀₀ₙ = 1.6m/s²

To find

• Weight of body on earth
• Weight of body on moon

Solution

• Weight of body on earth = mass × gₑₐᵣₜₕ
• Weight of body on earth = 10 × 9.8
• Weight of body on earth = 98

☯ Weight of body on earth = 98N

★ Mass of body on moon = Mass of body on earth = 10kg

• Weight of body on moon = m × gₘₒₒₙ
• Weight of body on moon = 10 × 1.6
• Weight of body on moon = 16N

☯ Weight of body on moon = 16N

Answer 2

Answer:

Given: weight=98N,g=9.8m/s

2

If ‘m’ is the mass of the body,

m=

g

W

=

9.8

98

=10kg

Mass remains constant

Mass on the moon is the same as the mass on earth =10kg

If weight on the moon is W

1

,

W

1

=mass×gonearth=10×1.6=16N
