Question

A particle is moving on a circular path with a constant speed V. Then change in its velocity after it has moved through an angle of 120° is

do it good with solution!! if it is right I will mark u as Brainliest !!

1) zero 2)2v 3)3v 4)√3 v

keep solution​

Answer 1

Answer:

Hope it helps

Explanation:

the linear velocity vector is perpendicular to the radius and has a magnitude of v always.

let the initial velocity vector be along +ve x axis.. so   v1 = v i.   When the body has traveled so that it describes an angle of 60° at the center of circle, the velocity vector = v2 will also turn by 60 deg. towards  +ve y axis.
