A particle is rotating in a circle of radius 1m with constant speed `4 m//s`. In time 1s, match the following (in SI units)
`{:(,"Column I",,,"Column II"),((A),"Displacement",,(p),8 sin 2),((B),"Distance",,(q),4),((C),"Average velocity",,(r),2sin 2),((D),"Average acceleration",,(s),4 sin 2):}`

Text Solution

Verified by Experts

The correct Answer is:
(A)-r, (B)-q, (C)-r (D)-p
`Rtheta=vt, theta=(4xx1)/1=4` radius

`:.` Displacement `=2R sin theta//2=2 sin 2`
Distance `=vt=4m`
Average velocity `=("Displacement")/("time")=2 sin 2`
Average acceleration `=("Change in velocity")/("time")`
`=(2xx4 sin 2)/(1)=8 sin 2`
