Question

What will be the displacement of an object if it cover two and half rounds of circular track

Answer 1

Answer:

displacement is equal to diameter or 2 times the radius of circle.

Explanation:

Where r is radius of circle. When particle covers half the circle, it is diametrically opposite to the starting point of its motion. Therefore shortest distance is equal to diameter of circle or 2× r is a displacement

Answer 2

Answer:

Diameter of circular track

Explanation:

When we complete a full circle from a point on a circular track the displacement becomes zero because there is no net position change. If you cover 2 rounds it is still zero. When you cover another half of it you reach the exact opposite point from your startimg point. Thus, it is the diameter
