A particle of mass 2 kg moves on a circular path with constant speed 10 m`//` s . Find change in speed and magnitude of change in velocity. Whan particle completes half revolution.

Explanation

To solve the problem step by step, let's break it down:

### Step 1: Understand the Problem
We have a particle of mass 2 kg moving in a circular path with a constant speed of 10 m/s. We need to find the change in speed and the magnitude of the change in velocity when the particle completes half a revolution.

### Step 2: Analyze Change in Speed
Since the particle is moving with a constant speed, the speed at any point during its motion remains the same. Therefore, the speed at the starting point (Point A) and the speed at the point after half a revolution (Point B) will both be 10 m/s.
