XII Physics Sample Paper
Can any of you here please provide me the latest sample paper of CBSE XII Physics exam?? Here I am sharing the latest sample paper of CBSE XII Physics exam A bar magnet of dipole moment M is cut into two equal parts along its axis. What is the new pole strength of each part. 1 Two polaroids are placed with their optic axis perpendicular to each other. One of them is rotated through 45° what is the intensity of light emerging from the second polaroid if I0 is the intensity of unpolarised light? 1 Sketch the graph showing the variation of applied voltage and photo electric current for (i) same frequency and two different intensities, and (ii) same intensity and two different frequencies. 1 What happens to the width of depletion layer of a p-n junction diode when it is (i) forward biased (ii) reverse biased. 1 Four equal charges +q, –q and +q are placed at the vertices P, Q and R of an equilateral triangle of side ‘a’. What is the electric potential at the Rest of the Questions are attached in below file which is free of cost Last edited by Neelurk; May 20th, 2020 at 02:35 PM. |
