Question

A particle is moving in a circular path of radius R what is the distance covered and displacement of the object after covering half of the circle​

Answer 1

Displacement will be

R+R=2R.........as diameter of a circle is 2×R(2×r radius) ........

the displacement is shortest path so in half circle the shortest path is Diameter....

Distance=πr(as circumference of semi circle)

distance =22/7×R

distance =22/7R or 3.14R
