A particle moves so that its position vector is given by r ^{\to} = \cos\\omegatx^{\^} + \sin \\omegaty^{\^}. Where \\omega is a constant. Which of the following is true?

Correct Answer is : Velocity is perpendicular to →r and acceleration is directed towards the origin

Velocity and acceleration both are perpendicular to r ^{\to}

Velocity and acceleration both are parallel to r ^{\to}

Velocity is perpendicular to r ^{\to} and acceleration is directed towards the origin

Velocity is perpendicular to r ^{\to} and acceleration is directed away from the origin
