Question

The mass and radius of the planet Jupiter are `2 xx 10^(27)` kg and `7 xx 10^(7)` m, respectively. Calculate the acceleration due to gravity on the surface of Jupiter.

Answer 1

Given
Mass of Jupiter, `M = 2 xx 10^(27) kg`
Radius of Jupiter, `R = 7 xx 10^(7) m`
Universal gravitation constant, `G = 6.67 xx 10^(-11) N m^(2) kg^(-2)`
Acceleration due to gravity on the surface of Jupiter,
`" "g = (GM)/(r^(2))=(6.67 xx 10^(-11) xx 2 xx 10^(27))/((7 xx 10^(7))^(2))=27.22 m s^(-2)`
