Question

A particle is moving in a circular path of radius ‛r’ What will be its displacement after half a circle is completed​

Answer 1

Answer:

(2*(22/7)*r)/2

Step-by-step explanation:

this is because the displacement is shortest distance covered so it will come

Answer 2

a particle is moving in a circular pathof radius r... since distance is the length of path covered therefore it will be equal to half the circumfrence i.e. 1/2 x 2pi r or pi x r and the displacement is equal to the distance between initial and final point.
