Question

particle is moving in a circle of diametro
14 metre. Calculated the distance and displacements​

Answer 1

Answer:

Circular motion

Explanation:

Radius = Diameter / 2 = 14 / 2 = 7

★ Distance

Circumference of circle = 2× π × Radius

= 14 π metres .

★ Displacement

» In circular motion ; the end and starting point are same so ; Displacement is zero .

Answer 2

Answer:

As the particle is moving in a circle, after completing a revolution, its displacement from initial position would be equal to 0 whereas the distance covered will be the circumference of the circle, i.e.

$- > 2\pi r \\ - > 2 \times \pi \times 7\\ - > 44 \: cm$
