Three particles \( \mathrm{P}, \mathrm{Q} \) and \( \mathrm{R} \) are situated at point
A on the circular path of radius \( 10 \mathrm{~m} \). All three particles move along different paths and reach point \( \mathrm{B} \) as shown in figure. Then the ratio of distance traversed by particles \( \mathrm{P} \) and \( \mathrm{Q} \) is :
(1) \( \frac{3}{4} \)
(2) \( \frac{1}{3} \)
(3) \( \frac{3 \pi}{4} \)
(4) \( \frac{\pi}{3} \)
\( \mathrm{P} \)
