Three particles P, Q and R are situated at pointA on the circular path

1.	Three particles P, Q and R are situated at pointA on the circular path of radius 10 m. All threeparticles move along different paths andreach pointB as shown in figure. Then the ratio of distancetraversed by particles P and Q is:
Answer» u know the perimeter of circle is 2pi r.here r is radius ________________________ now Point A all P,Q,R particle present , now point B is present on opposite side of A ________________________________P particle goes from A to B anticlockwise , so it travel 2pi10/2=10pi_________________________________Q particle goes clockwise , similarly to P is also be 2pi10/2=10pi_____________________ and R particle goes through the centre that why the distance travel by the R is 10+10=20(because 10 is the radius of circle) __________________________________ now ratio of P/Q=10pi/10pi=1 P/R=Q/R=10pi/20=pi/2

Answer»

u know the perimeter of circle is 2pi r.here r is radius ________________________

now

Point A all P,Q,R particle present ,

now point B is present on opposite side of A

________________________________P particle goes from A to B anticlockwise ,

so it travel 2pi*10/2=10pi_________________________________Q particle goes clockwise ,

similarly to P is also be 2pi*10/2=10pi_____________________

and R particle goes through the centre that why the distance travel by the R is 10+10=20(because 10 is the radius of circle)

__________________________________

now ratio of P/Q=10pi/10pi=1

P/R=Q/R=10pi/20=pi/2
