Question

a body is moving on a circular path of radius 7 cm what will be its displacement and the distance covered after half a circle​

Answer 1

Answer: Displacement : Diametre of the circle = 2 × 7= 14cm

Distance : πr = 22/7 × 7= 22cm

Answer 2

Answer:

Displacement is the shortest distance from the initial position to the final position

so the displacement after half a circle is 2r

2×7=14

Displacement = 14 cm
