hello dear
given :- radius of the circle = 5m
so total distance travelled in 3 revolutions = 2πr × 3
= 2 × 22/7 × 5 × 3
= 660/7m
= 94.28m (approx.)
now, what is displacement?
displacement is the shortest distance between the initial point to the final point.
here, the particle is moving in a circle, so the particle will come back to its same position after 3 revolutions. hence, displacement will be 0 as we know when a body comes back to its starting point.
