Question

If origin is at the centre of a circular field and a body covers one round of

the field, what is its Displacement and why?


Help me in this with ur correct answer​

Answer 1

Answer:

When a body moves from one position to another, the shortest distance measured between the initial and the final positions of the moving body in a particular direction is called displacement. The actual length of the path travelled by a moving body in a given interval of time is called the distance travelled by that body. So displacement of a body may be zero, though distance can be finite. For example, in case of circular motion if the body comes back to its initial position then distance travelled is finite but displacement is zero.

Answer 2

If the body covers one round of the field then the displacement of the body is as shown below.

• The displacement of a body can be described as the shortest distance covered by the body from one point to another point.
• In the given question, the origin is at the center of a circular field and a body covers one round of the field.
• So the body starts from one point and comes to the same point.
• Hence the distance between that point to the same point is zero. That means the displacement is zero.
• Therefore if a comes starts from one point and comes to the same point, then its displacement is zero and it is the same for this case too.
