Question

a particle is moving in a circular path of radius 10 m.what is its displacement after half a circle​

Answer 1

Answer:

20m.

Explanation:

Displacement is the straight line distance between the initial and final positions.

So, after completing half a circle, The displacement is equal to the diameter.

Answer 2

Answer: 20m

Explanation: Since the question is what is the "Displacement", we have to consider the shortest distance between the initial and final point.

Since the particle has made half a revolution, its starting and ending points can be considered to be on the ends of the diameter.

The diameter = 2*r = 2*10 = 20m
