Format: (of the question)

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
