JEE Mains · Physics · STD 11 - 2. motion in straight line
A sportsman runs around a circular track of radius \(r\) such that he traverses the path \(A B A B\). The distance travelled and displacement, respectively, are
- A \(2 \mathrm{r}, 3 \pi \mathrm{r}\)
- B \(3 \pi r, \pi r\)
- C \(\pi r, 3 r\)
- D \(3 \pi r, 2 r\)
Answer & Solution
Correct Answer
(D) \(3 \pi r, 2 r\)
Step-by-step Solution
