Question

Three particles P, Q and R are situated at point
A on the circular path of radius 10 m. All three
particles move along different paths and reach point
B as shown in figure. Then the ratio of distance
traversed by particles P and Q is:
​

Answer 1

Is it right or not..??

Answer 2

Hey there!

Given,

Radius of circular path = 10 m

Now,

Distance travelled by P = 3/4 × 2πr = 3πr / 2  m

Distance travelled by Q = 2 × r = 2r

Ratio of distance travelled =  {3πr /  2} : {2r}

                                            = 3π / 4      ←(Answer)
