A point moves in the plane `y` according to the law `x = A sin omegat, y = B cos omegat`, where`A,B & omega` are positive constant.
The acceleration of particle is given by [`:' barr` is position vector]

A

`bar(a) =- omega^(2) bar(r )`

B

`bar(a) = omega^(2) bar(r )`

C

`bar(a) = omega bar(r )`

D

`bar(a) =- omega bar(r )`

Text Solution

Verified by Experts

The correct Answer is:
A
`a_(x) = (dv_(x))/(dt), a_(y) = (dv_(y))/(dt), bar(a) = a_(x) hatj + a_(y) hatj`
