Question

plz answer correctly,I am asking this 7th time,no one answered,plz do help me now.The force of attraction between spheres of mass 40 kg and 15 kg if 10^-7 Newton .calculate the separation between them​

Answer 1

⭐⭐⭐Formula⭐⭐⭐

$Force = \frac{GmM}{r^{2} }$

Here, G is gravitational constant with value $6.67$ x $10^{-11$

m is the first mass

M is the second mass

r is distance of separation

⭐⭐⭐Process⭐⭐⭐

Substituting the values given, we get:

$r^2=\frac{GmM}{Force}$

$=\frac{G(40)(15)}{10^{-7}}$

$=6.67$ x $10^{-11$ x $6$ x $10^9$

=$0.4$ $m$

So, value of r will be :

$r=\sqrt{0.4}$

$\huge\boxed{Separation=0.63m}$
