# Two spherical bodies of mass M and 5M and radiiÂ  R and 2R respectively are released in free space with initial separation betwee

Two spherical bodies of mass M and 5 M and radii R and 2 R are released in free space with initial separation between their centres equal to 12 R If they attract each other due
to gravitational force only, then the distance covered by the smaller body before collision is:
a) 7.5 R
c)25R
b) 1.5 R
d) 4.5 R

have a look on this solution

As their centre of mass remains unchanged

$Mx_{1}=5Mx_{2}$   or  $x_{1}=5x_{2}$

$x_{1}+x_{2}=9R$

$x_{1}=7.5 R$

12R-3R=9R
