A particle is moving along a circular path with a constant speed `10 ms^-1`.What is the magnitude of the change in velocity of the particle ,when it moves through an angle of `60^@` around the center of the circle ?

Change in velocity
`|Delta bar|=sqrt(v_(1)^(2)+v_(2)^(2)+2v_(1)v_(2) cos(pi -theta))`
`=2 v "sin" (theta)/2 " "( :. +vecv_(1)|=|vecv_(2)|)=v`
`=(2xx10)xxsin (30^(2))=2xx10xx1/2`
`=10 m//s`
