Solution

The correct option is B
0m,440m

Distance $= 2 π r$

r =70 m

So, Distance $= 2 \times \frac{22}{7} \times 70$

=440 m

Displacement =seperation between the initial and final position, which is same in this case

$∴$ Displacement is zero

An athlete makes a complete round of a circular track of radius 70m.The displacement and distance covered in the process will be_______ and _________ respectively.

The correct option is B 0m,440m Distance =2πr r =70 m So, Distance =2×227×70 =440 m Displacement =seperation between the initial and final position, which is same in this case ∴ Displacement is zero
