A particle moves so that position vector is given by vecr = cos omega

1.	A particle moves so that position vector is given by vecr = cos omega t hat(x) + sin omega t hat(y). Where omega is a constant. Which of the following is true?
Answer» VELOCITY and ACCELERATION both are PERPENDICULAR to `vecr` Velocity and acceleration both are parallel to `vecr` Velocity is perpendicular to `vecr` and acceleration is directed towards the ORIGIN. Velocity is perpendicular to `vecr` and acceleration is directed away from the origin Answer :C
