Question

calculate the acceleration due to gravity on a planet whose mass is one fourth mass of the earth and the radius is one third the radius of earth

Answer 1

the acceleration is 1000 km per hour

Answer 2

g of earth=9.8m/s^2
let g of planet=g`
${g}^{.} = \frac{g \times 3}{ {4}^{2} }$
= 9.8×3/16
=98×3/160
=294/160
=1.8475m/s^2
