Question
Write scientific reason.
The weight of an object varies on different planets.
Solution
- The weight of an object of mass m on a planet is given by, Wp = mgp Where, gp = acceleration due to gravity at the planet.
- Also, acceleration due to gravity on the planet is given by gp = `"GM"_"P"/(("R"_"P")^2)`
where, MP = mass of the planet
and RP = radius of the planet - Since MP and RP are different on different planets, the weight of an object will be different on different planets even though its mass remains constant.
