Question

A gravitational force between two objects is 49n. How much distance between these object be decreased so that the force between them becomes double?

Answer 1

Hey mate

Heres ur answer..

Hope it helps

The electric force between an electron and a proton, between two electrons, or between two protons is much stronger than the gravitational force between any of these pairs of particles. Yet even though the sun and planets contain electrons and protons, it is the gravitational force that holds tha planets in their orbits around the sun. Explain this seeming contradiction.

Thank you....

Answer 2

Answer:

Gravitational force is given by:

 

         

where, G: gravitational constant

         m1,m2: the mass of the two objects

         r1: initial distance between them

 

Given,

F1 = 49 N

F2 = 2 x F1

F2  

gives, r22 = r12 / 2

        r2 = r1 / (√2) = 0.707r1 = (1-0.293)r1

Therefore, the distanced between them should be reduced by 29.3%
