A particle is moving on a circular path of radius r centre at O with constant speed v. What is the change in velocity after it has described an angle of 60? the ans is 'v' Share with your friends Share 0 Vaibhav T. answered this Dear Student, ∆v=v2+-v1The angle between v1→ and v2→ is 120°.∆v2=v2+v2+2v2 cos120°∆v2=2v2+2v2 cos120°∆v2=2v21-12∆v2=2v2×12∆v2=v2or, ∆v=v 2 View Full Answer
