Question

A body moving in a circle of radius r covers three/fourth of the circle. The ratio of distance and displacement is:​

Answer 1

Answer:

given ,

radius=R

then, circumference=2πr

now, body covers =3/4*2πr

=3/2πr

now,

displacement=√2r(by pythagoras theorem)

now , ratio=3/2πr/√2r

=3/√2π:1
