Question

In the figure a particle moves along a circular path of radius r and centre C. Diameter AB is perpendicular to radius UC. If it starts from U and goes in the anticlockwise direction then find the distance and displacement of the particle at point A.

Answer 1

Answer:

Distance=2$pie$r/4

               =pie r/2

Displacement= $\sqrt{2r^{2} }$

                =2r
