Question

A moving particle started from point A and stopped at point B. Calculate its distance and displacement.​

Answer 1

Answer:

π/3 and r

Explanation:

Distance of a complete circle = 2π = 360°

Here angle = 60° = 360°/6 = 2π/6 = π/3

Take the origin as point 'O'. By considering the triangle OAB,

all angles are 60° (equilateral triangle). So 3 sides are equal.

1 side is = to the radius of the circle. Here displacement is one side of the equilateral triangle joining A and B. So it should be also the radius = r.

Hope this helps.
