Question

when a particle is moving in a circular
hath of radius r. what is the
displacement of particle after
half a circle.​

Answer 1

Answer:

When a particle is moving in a circular path of radius r then the displacement of the particle is 2r.

Displacement at half path is the shortest distance between the initial and final point.

When the particle is moving in circular direction and completes half path then the tangent formed is equal to the diameter. The longest tangent which is equal to the two radius is known as diameter.

Displacement is the shortest path between two points. Distance is never be a displacement but the displacement can be the distance.
