Question

if the radius of the earth becomes 3 times its present value and its mass remain on changethen how would the weightof an object on the surface of the earth be affected?​

Answer 1

Explanation:

we know that g= GM/R²

so g is inversely proportional to R² so if R increase 3 times it's present value so g becomes 1/9 of its present value

so as the mass of earth is unchanged weight of the body is directly proportional to g hence weight also decrease 1/9 of its present value
