Physics MCQ on Addition and subtraction of Vector for NEET, JEE, Medical and Engineering Exam 2021

MCQ on Addition and subtraction of Vector: A vector quantity is defined as the physical quantity that has both direction as well as magnitude. A vector with the value of magnitude equal to one and direction is called unit vector represented by a lowercase alphabet with a “hat” circumflex. That is “û“.

In this post we are providing you MCQ on Addition and subtraction of Vector, which will be beneficial for you in upcoming NEET, AIIMS, JEE, WBJEE, Medical and Engineering Exams.
