Question

In each of your hands you hold a smartphone one has a mass of 0.130kg and the other has a mass of 0.200kg. if both phones create a force of 45 Newton on each other find the distance “r” (the radius) between them.

Answer 1

Answer:

0.00000019631 meters

Explanation:

Rearrange Fg=(Gm1m2)/r^2 for r

You get r=sqrt((Gm1m2)/Fg)

G=6.674*10^-11

r=sqrt((6.674*10^-11)(0.13)(0.2)/45)

r=0.00000019631 meters, or 0.00019631 mm
