Question

A particle is moving in a circular path of radius 7 m. The displacement of the particle after half a circle would be:​

Answer 1

Answer:

2r

Explanation:

Given after half the circle the particle will reach the diametrically opposite point i.e :from point A to point 6 And we know displacement is shortest path between initial and final point. Hence the displacement after half circle is 2r

Answer 2

Answer:

14m

Explanation:

The particle is moving in a circular path of radius 7 m and it covered half the circle. It means it covered half of the circumference.

We know that displacement is the minimum length from starting point to the ending point.

Hence, displacement = its length of diameter = 2r = 2×7 = 14m. Answer.
