As you are looking for the Central Board of Secondary Education class 12 Physics exam question paper , here I am providing list of few questions . 1. What is the direction of the force acting on a charged particle q, moving with a velocity v in a uniform magnetic field B__ ? 2. Name the part of the electromagnetic spectrum of wavelength 10-2 m and mention its one application. 3. An electron and alpha particle have the same de-Broglie wavelength associated with them. How are their kinetic energies related to each other? 4. A glass lens of refractive index 1.5 is placed in a trough of liquid. What must be the refractive index of the liquid in order to make the lens disappear? 5. A 500 mC Charge is at the centre of a square of side 10cm. Find the work done in moving a charge of 10 mC between two diagonally opposite points on the square. Central Board of Secondary Education class 12 Physics exam question paper      |
