Question

The gravitational force between two objects is 49 N.How much must the distance between these objects be decreased so the the force between them becomes dounle. →TOPIC-GRAVITATION →CLASS -9 ALL THE BEST​

Answer 1

Answer:

distance between the objects should be decreased by √2 times

Answer 2

Answer ¯\(◉‿◉)/¯

F = G m1 × m2/r² …(1)

Let new distance is R and then force is 2F,

We get, 2F = G m1 × m2/R²…(2)

Dividing equation (2) by (1)

2 = r²/R²

R² = r²/2

R = r/√2

Hence decrease in distance = r-r/√2 = r (√2 - 1)/√2

hope it helps you
