Answer:
Explanation:
given mass on earth =98 kg
gravitational pull on mars =3.711 m/s2
gravitational pull on venus =8.87 m/s2
weight of the body on mars =weight on earth/9.81 m/s2 *3.711 m/s2
W=98 kg*3.711 /9.81m/s2
W=37.07 kg
weight on the venus =weight on earth*8.87 m/s2 /9.81 m/s2
W= 98 kg*7.87 m/s2/9.81 m/s2
W=78.62 kg
