Question

Two spherical bodies of mass M and 4M and radii R and 3R are released in free space with initial separation between their centres equal to 9R.

Answer 1

Mx=4M(5-x)

Mx=20M-4Mx

5Mx=20M

x=4= 4R

So for COM:

M(4R)+4M(R)/5M

=8R/5 from mass 1

From mass 2

4Mx=M(5-x)

4Mx=5M-Mx

x=1 = 1R

So COM:

={4M+M(4)}R/5M

8R/5

Answer 2
