Question

A particle moves on the cirumference of a circle of radius r with speed v . find the displacement after half and full time period? ​

Answer 1

Answer:

after half time 2r, after full time 0.

Explanation:

If a particle moves on circumference of circle then displacement after half time:

time taken = 1/2 of time of complete revolution

displacement= diameter= 2r. (as particle will cover only half of track, then change in its position from initial to final will be 2r)

If a particle moves on circumference of circle then displacement after full time:

after full time, the particle would be back to its initial position, so displacement is zero.
