Question

The force F of attraction between two bodies varies jointly as the weights of the two bodies and inversely as the square of the distance between them. Express this fact as a variation using c as a constant. Use M1 and M2 for the weights of the two bodies.

Answer 1

We can write this as

F = c  M1 M2 / d^2    where d = distance between the bodies

Answer 2

Answer:

I think the answer is $c=F(d^2)/(m_1m_2)$

Step-by-step explanation:

REMEMBER: The formula for joint variation is:

$c=y/xz$ OR $y=cxz$.

Substitute:

$F=Km_1m_2/d^2$

then change to:

k= constant, they want you to use "c" instead:

$c=F(d^2)/(m_1m_2)$

Hope this helps!
