On planet x, an object weighs 7.04 n. onplanet b where the magnitude of the free-fallacceleration is 1.91g(whereg= 9.8 m/s2isthe gravitational acceleration on earth), theobject weighs 25.74 n. the acceleration of gravity is 9.8 m/s2.what is the mass of the object be on earth? answer in units of kg.

Explanation:

On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.

We have

           Weight = Mass x Acceleration due to gravity

On planet B

           25.74 = Mass x 1.91 g

           25.74 = Mass x 1.91 x 9.81

           Mass = 1.37 kg

Mass is constant for an object. It will not change with location.

Mass of object in Earth = Mass of object in Planet B

Mass of object in Earth = 1.37 kg
