Question

A particle is moving in a circular path of radious r the displacement after half a circle would be

Answer 1

Answer:

The displacement after half a circle would be 2r[2 * radius}

Explanation:

This is because when a stone tied[consider it as object]to a string is made to move round a circle the distance between the string being held by our hand and the stone is counted as the radius[starting position]. moving it half a circle round means the shortest distance[displacement]between starting point and the position[half a circle or final position], which is 2 times the radius[r].

hence the answer is 2r
