3ThreeparticlesP,QandRaresituatedatpointA on the circular path of radius 10 m. All threeparticles move along different paths and reach pointB as shown in figure. Then the ratio of distancetraversed by particles P and Q is |
| Answer» <p>u know the perimeter of circle is 2pi r.here r is radius ________________________§__§</p><p>now</p><p>Point A all P,Q,R particle present ,</p><p>now point B is present on opposite side of A</p><p>________________________________P particle goes from A to B anticlockwise ,</p><p>so it travel 2pi*10/2=10pi_________________________________Q particle goes clockwise ,</p><p>similarly to P is also be 2pi*10/2=10pi_____________________§§§</p><p>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)</p><p>__________________________________</p><p>now ratio of P/Q=10pi/10pi=1</p><p>P/R=Q/R=10pi/20=pi/2</p> | |
