 Hi and welcome to the session. Let us discuss the following question. Question says, if A vector and B vector are two collinear vectors, then which of the following are incorrect? A, B vector is equal to lambda multiplied by A vector for some scalar lambda. B, A vector is equal to plus minus B vector. C, the respective components of vector A and vector B are proportional. D, both the vectors, vector A and vector B have same direction but different magnitudes. We have to choose the correct answer from A, B, C and D. Let us now start with the solution. First of all, let us understand what are collinear vectors? Now, two or more vectors are said to be collinear if they are parallel to the same line irrespective of their magnitudes and directions. So, we can write two or more vectors are said to be collinear if they are parallel to the same line irrespective of their magnitudes and directions. Clearly, we can see collinear vectors should satisfy this condition that is they should be parallel to the same line. And clearly, we can see here that collinear vectors can have any magnitude and any direction. They may have same or different directions. They may have same or different magnitudes. Clearly, we can see here options A, B and C are true for collinear vectors. Now, let us consider option D. Here, option D states that both collinear vectors, vector A and vector B have same direction but different magnitudes, which is not true always. So, this statement is incorrect statement. So, our correct answer is D. So, this is our required answer. This completes the session. Hope you understood the solution. Take care and have a nice day.
