A circle of radius unity is centered at thet origin. Two particles tart moving at the same time from the point `(1, 0)` and move around the circle in opposite direction. One of the particle moves anticlockwise with constant speed `v` and the other moves clockwise with constant speed `3v`. After leaving `(1, 0)`, the two particles meet first at a point `P,` and continue until they meet next at point `Q `. The coordinates of the point `Q` are

Explanation

we have given that the radius of circle is one unit

r=1

we know equation of circle is

`x^2+y^2=1`

`(vt+3vt)=2pir`

`4vt=2pi`

`t=(2pi)/(4v)`

`t=pi/(2v)`
