SET -2 Section A Q.1) Draw the graph showing the variation photoelectric current with applied voltage for two incident radiations of equal frequency and different intensities. Mark the graph for the radiation of higher intensity. (1) Q.2) A proton and an electron travelling along parallel paths enter a region of…

SET -1 Section A  Q.1) A proton and an electron travelling along parallel paths enter a region of uniform magnetic field, acting perpendicular to their paths. Which one of them will move in a circular path with higher frequency? (1) Q.2) Name the electromagnetic radiation used for (a) water purification, and…
