Question

A planet has mass of 20% more than earth and radius is 20%than earth then accleration due to gravity

Answer 1

Answer:

Explanation:

g=GM/R²

MASS OF PLANET=20/100*MASS OF EARTH

RADIUS OF PLANET=20/100* RADIUS OF EARTH.

(g OF PLANET)/g OF EARTH=(G*MASS OF PLANET*R² OF EARTH)

                                                  ----------------------------------------------------------

                                                   (G*MASS OF EARTH*R² OF THE PLANET)

                                                G*0.2 MASS OF  EARTH*R²

                                             =  ---------------------------------------------

                                                 G*MASS OF EARTH*0.2*0.2*R²

                                               =I/0.2

g  OF PLANET=5 g OF THE EARTH.
