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

$\frac{1}{\pi}$

Explanation

Solution

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