Question

tell only right answers​

Answer 1

The distance travelled from A to B will be the circumference of circle from A to B

• Now, as you can see the circumferene(AB) compose only 3/4 circumference of the whole circle, thus we will calculate the distance traveled likewise;

= ¾ × circumference of circle

= ¾ × 2πr

= 3/2πr

Therefore, the distance traveled is 3/2πr.

Now, for displacement, it is something like the shortest distance between two points kinda shortcut;

Let the center of the circle be O,

• So, we can reach A to B, if we will at first walk through AO and then OB, thus our displacement will be;

= AO + OB

• Both are radius so,

= r + r

= 2r

Therefore, the displacement is 2r.
