a particle moves in a circle with a uniform speed when it goes from a point A to a diametrically opp point B the momentum of the particle changes by PA-PB=2kgm/s(j) and the centripetal force acting on it changes by FA-FB=8N(i) where i and j r unit vectors then angular velocity of the particle is
[ans:4 rad/sec]
rates assured............

FAILURE IS NOT FALLING IN LIFE BUT NOT RISING AGAIN AFTER FALLING!!!!!!
I LIKE WAVES NOT BECAUSE THEY RISE AND FALL..
BUT BECAUSE EVERYTIME THEY FALL THEY RISE AGAIN!!!!!!!
