You can get the 2nd Year Chapter 7 Maths Vectors MCQs with Answers here. So, if you have started entry test preparations, then you must have to prepare for all the subjects, especially for Maths. It has a huge impact on your results. If you do very well in all the subjects and can’t take good marks in Maths, then it would be a very difficult situation to get good marks. The 7th Chapter is about Vectors and hopefully, you know what are vectors. They are the physical quantities having direction and magnitude. There are several types of vector. There are different laws applicable to them while addition. You will study the applications and properties of the vector. So, this is a short introduction to this chapter. Hopefully, you got the important information. Now, scroll down to get the important MCQs of this chapter.
