Question

A boy runs along the circular track of radius R with constant
speed r. If the magnitude of his displacement is 2 R after
covering a revolutions, then n can be

4.5
3.25
2
4​

Answer 1

Answer:

4.5

Explanation:

For n = 2 , 4 displacement will be zero

For n = 3.25 displacement will be R root 2

For n = 4.5 displacement will be 2R because the boy will at just opposite side.
