Question

A particle starts from (0,0) and moves along y-axis to a point (0,26) m and then to (0, -26) m. The ratio between distance and displacement is

• A. 1
• B. 0
• C. $\infty$
• D. 3

Answer 1

Answer: (D)

3

Answer 2

Distance moved = 26 + 26 + 26 = 78 m

Displacement = 26 - 26 - 26 = - 26 m
Magnitude of displacement = 26 m
$\therefore$ $\frac{\text{Distance}}{\text{Magnitude of displacement}} = \frac{78}{26} = 3$
