Question

a body starting at a point say A, reaches, say B , ahead in a straight line and returns back to A , then there is (a) positive displacement (b) zero displacement (c) negative displacement (d) cannot be said​

Answer 1

Answer:

(b) Zero displacement

Explanation:

Answer 2

Answer:

When a body from one point travels to another point and later returns to the original position, then there is (b) zero displacement.

Explanation:

• Displacement refers to the change in the position of an object in a particular direction.
• It is a vector quantity, that has both magnitude and direction.
• Therefore, when the body travels from one point A to point B and then returns to point A, displacement becomes zero.
• When the initial and final position of a body is the same, the displacement is said to be zero.
