The vector quantity is: a) Power b) Work c) Momentum d) Electrostatic potential
Answer (1)
In physics, vectors are quantities that have both a magnitude and a direction. In the given multiple-choice options, we need to identify which one is a vector quantity.
Let's analyze each option:
Power : This is a measure of how much work is done in a specific amount of time. It is a scalar quantity because it only has magnitude, with no direction associated.
Work : This represents the energy transferred by force over a displacement and is also a scalar quantity. It involves magnitude but no direction.
Momentum : This is defined as the product of an object's mass and its velocity. Since velocity is a vector (having both magnitude and direction), momentum is also a vector quantity. It points in the direction of the velocity of the object.
Electrostatic potential : It refers to the potential energy per unit charge at a point in an electric field. This is a scalar quantity, as it does not involve direction.
Hence, the correct answer is c) Momentum , which is the vector quantity among the options provided.
