Question

A car moves on a circular road of radius $2km$. After it completes $4$ complete rounds,

• A. distance and displacement both are zero
• B. distance and displacement both are non-zero
• C. distance is zero, displacement is non-zero
• D. none of the above is correct

Answer 1

The correct option is D none of the above is correct

After the car completes $4$ complete rounds, its initial and final positions are same. So, its displacement is zero.
And the distance travelled is $4$ times the perimeter of the circular road, hence is non-zero.
