Among the following, which is not a vector quantity?
Among the following, which is not a vector quantity?
The correct option is B Distance
Explanation for the correct option:
(b): Distance has no particular direction.
1. The length of the path traveled by a body in a certain interval of time in any direction is called distance.
2. Distance has only magnitude.
Explanation for the incorrect option:
(a) Displacement is defined as the change in the position of an object. It has magnitude and direction and obeys vector algebra.
(c) Acceleration is defined as the rate of change of velocity of an object in a particular direction. It has magnitude and direction and obeys vector algebra.
(d) Velocity is defined as the rate of change of displacement of an object in a particular direction. It has magnitude and direction and obeys vector algebra.
Thus, among the following, distance is not a vector quantity.
Hence, Option (B) is the correct answer.
