Question

what is the displacement of bike if it make a round of a circular park of radius 70m
1. 0m
2. 70m
3. 140
4. 440​

Answer 1

Answer:

It is a vector quantity. For example, if a body moves along a circle of radius r and covers half the circumference, then displacement is given by s=2r. In one-dimensional motion displacement of the object will be the shortest distance between final and initial point.

Hope this helps you☺

Answer 2

option a) zero

as displacement is vector quantity and depends upon both direction and magnitude so, displacement is zero coz both final and intial position is same
