Question

Following is not a vector
(A) Linear momentum
(B) Electrical field
(C) Kinetic energy
(D) Acceleration

Answer 1

To get answer of this question,we are going to apply the concept of scalar and vector quantity.The term that does not have direction but can have magnitude is called scalar quantity and the term that have both magnitude and direction is called as vector quantity.

Complete step by step answer:
-An amount that has both magnitude and direction. It is normally spoken to by a bolt whose heading is equivalent to that of the amount and whose length is relative to the amount's magnitude. Albeit a vector has size and heading, it doesn't have position. That is, the length of its length isn't changed, a vector isn't adjusted in the event that it is uprooted corresponding to itself.
-Linear momentum is a vector quantity. For a molecule with mass, the linear momentum rises to mass occasions speed, and speed is a vector quantity while mass is a scalar amount. A scalar increased by a vector is a vector. Hence, linear momentum is vector quantity.
-Electric field at any point is calculated in terms of electric field intensity. Electric field can be defined as the force experienced by a unit positive charge kept at that point. Since force is vector quantity, the electric field is vector quantity.
-Acceleration is an increase in velocity with time. Velocity is a vector quantity since it has both magnitude and direction. Hence, acceleration is also a vector quantity.
-Kinetic energy is produced when any object experiences motion. It is the energy of mass of an object in motion.Since it has no direction it cannot be vector quantity.

Hence, option (C) is the correct answer.

Note: Sometimes students get confused between the scalar and vector quantities and thus make a blunder in simple questions also.Hence,always keep in the find the definitions of these quantities.
