Q8 of 111 Page 250

The displacement of a particle is given by The motion of the particle is

If we take the magnitude of , then


Where . So particle is moving at a fixed distance ‘A’ from the origin, which makes the conclusion that the particle is on the path which is circle. Also, it can be seen from the equation that phase difference between x and y terms are.
