Question

# A body moves along a curved path of a quarter circle.Calculate the ratio of distance to displacement :

A
11:7
B
7:11
C
11:72
D
7:112

Solution

## The correct option is D $$11:7\sqrt{2}$$Perimeter of circle is $$2\pi R$$Hence, distance on the quarter circle is $$d$$ =$$\dfrac{2\pi R}{4} = \dfrac{\pi R}{2}$$Displacement is $$D$$ =$$R\sqrt{2}$$$$\therefore$$ $$d:D = \dfrac{\pi R}{2} :R\sqrt{2}$$$$\pi = \dfrac{22}{7}$$$$d:D = 11:\sqrt{2}\times 7$$Physics
