Question

if an object covers half of a circular path of radius R cm, its displacement will be R cm.true or false​

Answer 1

Answer:

False.

Explanation:

If an object covers half of a circular path of radius R cm, its displacement will be 2R cm.

Displacement is the shortest distance covered by the object between the initial and final positions. If the object covered half the distance of a circular path then the object will be diametrically opposite to its initial position. So the straight line distance between the initial and final positions will be equal to the diameter of the circle. Since the diameter is twice the radius we can say that the displacement made by the object will be 2R.
