A particle moves in a circle with a uniform speed, when it goes from a point A to a diametrically opposite point B, the momentum of the particle changes by \[{{\vec{P}}_{A}}-{{\vec{P}}_{B}}=2kg-m/s\left( {\hat{j}} \right)\]and the centripetal force acting on it changes by \[{{\vec{F}}_{A}}-{{\vec{F}}_{B}}=8N\left( {\hat{i}} \right)\] where \[\hat{i},\]\[\hat{j}\] are unit vectors. Find the angular velocity (in rad/s) of the particle.
