Important Physics Questions for NDA Exam:- Friends, when we talk about the NDA exam, the question definitely comes to our mind that what subjects will be asked in the written examination of NDA. For which we collect information about all subjects related to the NDA examination. And try to make sure that we have information about all the topics asked in each subject. So, today, through this article of ours, we give you information about one of the most important subjects in the NDA exam. At the same time, you will also be informed that what important questions are asked from the subject of physics.

In the NDA exam, the candidates are asked questions based on the CBSE syllabus. In which candidates have questions from the subject of Physics in the 11th and 12th exam topics. In today’s article, we will give you information about all the topics related to Physics in the CBSE syllabus and questions required for NDA. So let’s start and give you information about important physics questions.
