Question

particle is moving in a circle of diameter 5 metrefind out distance at and displacement covered after taking 3 revolution ​

Answer 1

Answer:

displacement = 0

distance = 47.12 mtr

Explanation:

displacement is a vector quantity. the object has come back to its original position even after 3 laps, hence the displacement is zero.

as of distance, its a scalar quantity.

radius = 5/2 = 2.5

circumference of the circle = 2 x 3.14 x 2.5 = 15.7

3 laps of the circle = 15.7 x 3 = 47.12
