Question

three particles P Q R are situated at a point a on the circular path of radius 10 metre all three particles move along different addresses at the point be shown in the figure then ratio of distance travelled by the particle P and Q is​

Answer 1

Answer:

$\frac{3\pi}{4}$

Explanation:

as Q is moving radially so

distance travelled by Q=2r

as P is moving along the arc

and, angle made by P at centre=3π÷2

so the distance travelled by P=2π× r ×(3π÷2)÷(2π)

=3π÷2× r

ratio of distance travelled by P and Q= [3π÷2 r]/[2r]

=3π/4

follow if that helped.
