(a)
For translatory motion the force should be applied on the centre of the mass of the body. So we have to calculate the location of centre of mass of ‘
’ shaped object.
Let mass of rod 
is 
so the mass of the rod 
will be 
Let 
is the centre of mass of rod 
and 
is the centre of mass of rod 
. We can consider that whole mass of the rod is placed at their respective centre of mass 
mass 
is placed at 
and mass 
is placed at

Taking point ‘
’ at the origin position vector of point 
and 
can be written as 
and 
and 
Position vector of centre of mass of the system
Hence the distance of centre of mass from
