Question

A body covered a distance
of 5m along a circular track if it completes half of its circumference.Its displacement is​

Answer 1

Answer:

displacement is 3m

Step-by-step explanation:

circumference for half circle= πr

πr=5

22/7r=5

r=5*7/22

r=1.5m

displacement = diameter

d=2r

d= 2*1.5

d=3m

therefore

displacement is 3m

I hope my answer helps you☺☺

Answer 2

Answer: Displacement made by the body is $\frac{10}{\pi }$ m

Step-by-step explanation:

circumference of circle = 2πr

circumference of half circular track = πr

distance covered by the body= 5m

distance covered = circumference of half circular track

5=πr

r = $\frac{5}{\pi }$

displacement = 2r

displacement= $\frac{2*5}{\pi }$

displacement = $\frac{10}{\pi }$m

So, displacement covered by the body is $\frac{10}{\pi }$ m
