A Uniform Rod

Q. A rod of length $10\text{m}$ is inclined on the wall at an angle ${37}^{\circ }$ with horizontal.


Find out position of centre of mass of the rod assuming the wall to be along $y-$ axis and foot of the wall as the origin.

1. $(5\text{m},4\text{m})$
2. $(4\text{m},5\text{m})$
3. $(5\text{m},3\text{m})$
4. $(4\text{m},3\text{m})$
