AB is diameter of circle of radius `r`. A particle starting from A completes two and half revolution. Calculate the distance travelled by the particle and its displacement

Text Solution

Verified by Experts

Distance travelled ` = 2(1)/(2) xx (2 pi r) = 5 pi r`
After completing two and a half revolution, particle is at `B`.
`:.` Displacement `= vec(AB) = 2vec (r )`
