Question

# A shaped object with dimension shown in the figure, is lying on a smooth floor. A force is applied at the point parallel to , such that the object has only the translational motion without rotation. Find the location of with respect to .

## The correct answer is:

### For translator motion the force should be applied on the centre of 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 rod will be 2.

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 points can be written as

and

Position vector of centre of mass of the system
