YCMOU B.Tech EE Applied Physics question paper Time: 180 minutes Marks: 80 Instructions for the Students : 1) All ques. are compulsory. 2) "Long ans kind ques. (LAQ)" is a supply kind ques. of 20 marks which requires a typical ans of about 60-80 lines in about 32-,40 minutes. 3) "Short ans kind ques. (SAQ)" i~ a supply kind ques. of five marks which requires a t:ypical answe,r of about 15-20 lines in about 08-10 minutes. 4) Use of a non-programmable kind of scientific calculator is allowed. 5) Draw neat diagrams wherever necessary. 6) presume suitable data if necessary . Long ans kind Questions'(LAQ's) 1)Define fundamental volumes. Write the rules and conventions to be obeyed when SI units are used. [marks 5] 2)Write a note on the vector product of 2 vectors. [marks 5] 3)What is energy ? describe kinetic energy and potential energy. provide one example of every. [marks 5] 4)Define angular velocity and angular acceleration of uniform circular motion. Write down their SI units and mathematical formula. [marks 5] 5)Write a few features of the centre of gravity. [marks 5] 6)Derive an expression for the moment of inertia of a hollow cylinder having an inner radius Rl and outer radius R2 when the axis of rotation is the identical as the axis of the cylinder.
