A cyclist starts from the point PP of a circular ground of radius 2 km2 \mathrm{~km} and travels along its circumference to the point S\mathrm{S}. The displacement of a cyclist is:

Show answer and solution

Answer: (A) 8 km\sqrt{8} \mathrm{~km}


∴\therefore Displacement =R2=22=8 km=\mathrm{R} \sqrt{2}=2 \sqrt{2}=\sqrt{8} \mathrm{~km}
