Question

.A particle moves over three quarter (3/4th) of a circle of radius 'r' cm calculate magnitude of its distance

Answer 1

Answer :

A particles moves over three quarter og a circle of radius 'r'.

We have to find distance covered by particle$.$

◈ What is distance (✊)

Distance is defined as the actual length of path which is covered by moving object.

It's a scalar quantity having only magnitude. It can't be negative or zero.

⇒ Distance = 3/4 × 2πr

⇒ Distance = 3πr/2
