heyy user ur answer.......
Given:Weight of object on Mars = 200N Radius of Earth = 6400 kmRadius of Mars = 3200 kmMass of Earth (Me) = 10 x Mass of Mars (Mm)⇒Me/Mm = 10We Know That g α m/R²⇒ge/gm = (Me/Mm)(Rm/Re)²⇒ge/gm=10 x (3200/6400)²⇒ge/gm = 10/4⇒ gm = (2/5) ge Weight of object on Earth = M x ge = 200 NWeight of object of Mars = M x gm⇒ M[(2/5)ge]⇒ Mge x (2/5)= (200 x 2)/5 = 80 N∴Weight Of Object on Mars = 80N
