What will be the coordinates of the centroid (C) of the semi-circular lamina (OAB) shown in the figure? [‘O’ is the origin, ‘R’ is the Radius of semi-circular lamina]
1
\(\left( {R,\frac{{4R}}{{3\pi }}} \right)\)
2
\(\left( {R,\frac{{2R}}{{3\pi }}} \right)\)
3
\(\left( {\frac{R}{2},\frac{{3R}}{{2\pi }}} \right)\)
4
\(\left( {\frac{{4R}}{{3\pi }},R} \right)\)
