Mona weighs $750 \, N$ on Earth:
$(i)$ On the planet Mars,the force of gravity is $38 \%$ of that of Earth. How much will Mona weigh on Mars?
$(ii)$ What will be Mona's mass on Earth (take $g = 10 \, m s^{-2}$)?
$(i)$ On the planet Mars,the force of gravity is $38 \%$ of that of Earth. How much will Mona weigh on Mars?
$(ii)$ What will be Mona's mass on Earth (take $g = 10 \, m s^{-2}$)?
(N/A) $(i)$ The weight on Mars is $38 \%$ of the weight on Earth.
Weight on Mars $= 0.38 \times 750 \, N = 285 \, N$.
$(ii)$ The relationship between weight $(W)$,mass $(m)$,and acceleration due to gravity $(g)$ is given by $W = m \times g$.
Given $W = 750 \, N$ and $g = 10 \, m s^{-2}$.
Mass $m = W / g = 750 / 10 = 75 \, kg$.
Therefore,Mona's mass on Earth is $75 \, kg$.
