A particle is rotating in the x-y plane on a circle of radius 2 m. At a certain instant, the particle is at point P and its acceleration is 6î - 8ĵ. Which of the following values is incorrect at this moment?
1) Magnitude of acceleration = 10 m/s²
2) Direction of acceleration = -53.13° with respect to the positive x-axis
3) Magnitude of velocity = 4 m/s
4) Direction of velocity = -45° with respect to the positive x-axis
