Question

in the earth shrinks of its radius and mass remains same then the weight of an object earth will become​

Answer 1

Explanation:

Weight is the product of mass and acceleration due to gravity.

i.e. W=mg

m(mass of earth is constant) --(Given)

g=GM/R^2

Here value of R decreases.

But R is inversely proportional to g.

Therefore the value of g will increase.

With increase in value of g the value of W(weight) will also increase.

Since W(weight) is directly proportional to g.
