The position vector of a particle is `r = a sin omega t hati +a cos omega t hatj`
The velocity of the particle is

A

parallel to position vecor

B

perpendicular to position vector

C

directed towards origin

D

directed awa from the origin

Text Solution

Verified by Experts

The correct Answer is:
B
Given, `r = (a sin omegat) hati +(a cos omegat) hatj`
`:. V = (dr)/(dt) = (-a omega sin omega t) hatj +(a omega cos omega t) hati`
`r. v = 0 rArr r _|_ v`
