Physics Class 12 Sample Paper

 

Q1. You are asked to measure e.m.f of a cell. Which instrument will you use? A high resistance Voltmeter or Potentiometer and why? 

Q2. An electron and a proton, having equal momenta, enter a uniform magnetic field at right angles to the field lines. What will be the ratio of their trajectories? 

Q3. Why is short wave band used for long distance Radio Broadcast? 

Q4. If a wire is stretched to double its original length without loss of mass, how will the resistivity of the wire be influenced?

05. When light travel from a rarer to denser medium, the speed decreases. Does this decrease in speed imply a decrease in the energy carried by the light wave? Justify your answer. 
 
06. If the potential difference across a capacitor is doubled, what happens to :
(a) The charge on the capacitor and
(b) The energy stored in the capacitors. 
 
07. Give block diagram of basic units of all communication system.

(a) One that draws an rms current of 10 A or
(b) One that draws a Peak current of 12 A ? 
 
9. Write Einstein’s photoelectric equation. Explain the terms.
(i) Threshold frequency and
(ii) Stopping potential.
 
10. Suggest a suitable method to invert an image
(i) Without change in size.
(ii) Without change in size and without deviation from its original direction of view.
Explain how the same is achieved? 
 
11. Define Self-inductance of a coil. Show that magnetic energy required building up the current I in a coil of self-inductance L is given by ½ LI2 
 
12. ‘n’ identical capacitors when joined in series give an effective capacitance of C Units. What will be the capacitance if the capacitors are now placed in parallel combination?
 
13. Show that the power due to the force exerted by the magnetic field on a moving charge is zero. 
Or
Find the ratio of the de-Broglie wavelength, associated with
(i) Protons, accelerated through a potential of 128 V and
(ii) α - particles, accelerated through a potential of 64 V
 
14. Two identical cells of emf 1.5V each joined in parallel, provide supply to an external circuit consisting of two resistors of 17 Ω. Each joined in parallel. A very high resistance voltmeter reads the terminal voltage of the
