Question

What is the distance of centre of mass of a half ring from centre if the ring has radius = 0.5 m. [XI]

• A. $\frac{1}{\pi }$
• B. $\frac{1}{3\pi }$
• C. $\frac{2}{3\pi }$
• D. $\frac{1}{2\pi }$

Answer 1

Answer: (A)

Distance of center of mass of half ring from center
$y=\frac{2R}{\pi }=\frac{2\times 0.5}{\pi }=\frac{1}{\pi }$
