Question

A body is describing circular path. When it completes
one and half of a circle, the ratio of distance travelled to
its displacement is
1) 33:7 2) 7:11 3) 11:7 4)7:22
​

Answer 1

Answer:

33 : 7

Explanation:

Let distance = d

and, Let displacemnt  = s

$\frac{d}{s} \\\\= \frac{2\pi r + \frac{2\pi r}{2} }{diameter} \\\\= \frac{2\pi r + \pi r}{2r} \\\\= \frac{3\pi r}{2r} \\\\=\frac{3\pi }{2} \\\\= \frac{3\times22}{2\times7} \\\\= \frac{33}{7} \\\\= 33 : 7$
