Question

A particle is moving in a circular path of radius r.the displacement after covering half a circle would be
a. zero
b.πr
c.2r
d 2πr​

Answer 1

We know that Displacement is the shortest route b|w 2 points

So when particle covers half a circle

the distance covered would be

$\frac{2\pi r}{2}=\pi r$

But displacemwnt would be

Displacement = Diameter =2R
