A body covered a distance of 5 m along a circular track if it completes half of it's circumference.its displacement is
(1) 5m
(2) 10m
(3) 35/11m
(4) 35/22m
Answers
Answer:
(3) 35/11m
Explanation:
1/2 circumference=22/7 × r
5m=22/7 × r
(5×7)÷22=r
Displacement = Diameter
= ((5×7)÷22)×2
= 35/11m
The value of displacement is 35/22 m.
Given:
A body covered a distance of 5 m along a circular track.
It completes half of its circumference.
To Find:
The value of displacement.
Solution:
We are required to find the value of displacement.
The body travels on a circular track and it completed half of its circumference.
Circumference of circular track = 2πr
Half circumference of circular track = πr
Distance travelled = 5m
The distance traveled is equal to the Half circumference of a circular track.
πr = 5
r = 5/π ------(1)
π = 22/7 substitute in the equation(1)
r = 5×7/22
r = 35/22 m
Therefore, The value of displacement is 35/22 m.
