Which of the following is not a vector quantity
A. Weight
B. Velocity
C. Acceleration
D. Force
Answer: Option A
Solution (By Examveda Team)
Option A: WeightWeight 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.

A. Density of metal can’t be determined
B. Metal is twice as dense as water
C. Metal will float in water
D. Metal is twice as dense as unknown fluid
Coulomb friction is the friction between
A. Bodies having relative motion
B. Two dry surfaces
C. Two lubricated surfaces
D. Solids and liquids
Weight:
Weight 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.
ALL OPTIONS ARE VECTOR QUANTITIES
all are vector
