Which of the following is not a vector quantity
Answer & Solution
Correct Answer:
Option
A
Option A: Weight
Weight is a vector quantity as it has both magnitude and direction (directed towards the center of the Earth).
Option B: Velocity
Velocity is a vector quantity because it represents both the speed and direction of an object.
Option C: Acceleration
Acceleration is also a vector quantity, as it defines the rate of change of velocity and includes direction.
Option D: Force
Force is a vector quantity, as it has both magnitude and direction, acting on an object to cause acceleration.
Correct Explanation: While all the options might seem to have directional attributes, **Weight** is actually a vector quantity.
There is no option in the given choices that represents a scalar (non-vector) quantity.

LoginWeight is the force exerted on an object due to gravity. It has both magnitude and direction (toward the center of the Earth), making it a vector quantity.
Velocity:
Velocity is a measure of the rate of change of position with direction. It has both magnitude (speed) and direction, so it is a vector quantity.
Acceleration:
Acceleration is the rate of change of velocity with time. It also has both magnitude and direction, making it a vector quantity.
Force:
Force is an interaction that causes a change in the motion of an object. It has both magnitude and direction, so it is a vector quantity.
