Question

25.
A body moves on three quarters of a circle of radius r.
The displacement and distance travelled by it are:
(a) displacement=r distance = 3r.
(b) displexerenL =√2r, distance = 3πr/2
(c) displacement - 2r, distance=3πr/2
(d) displacement=0.distance = 3πr/2​

Answer 1

Answer:

it's (b)

Explanation:

use Pythagoras theorem for displacement

Answer 2

Answer:

Opt d

Because it's a circle and it reaches the same position after 3 rounds so the displacement is 0

For distance use circumference of the circle and multiply by 3

So the answer is opt d
