Physics Practical Class 11

The Central Board of Secondary Education provides a well-structured syllabus for the practical examination. The physics practical consists of various interesting experiments which are also essential for their 12th standard practical exam. So students must perform their physics practical exams properly to perform better in the final exam. The Physics Practical Class 11 is given here to help students prepare for their exam. The physics practical exam for class 11 carries a total of 30 marks. Along with the projects and experiments, students must also prepare for the viva questions on the experiment which carries 5 marks. Students should practice graphs and diagrams as they are essential parts of the exam.

Class 11 Physics Experiments

Section A

1. To measure the diameter of a small spherical/cylindrical body using Vernier callipers.

2. To measure internal diameter and depth of a given beaker/calorimeter using Vernier callipers and hence find its volume.

3. To measure the diameter of a given wire using screw gauge.

4. To measure the thickness of a given sheet using screw gauge.

5. To measure the volume of an irregular lamina using screw gauge.

6. To determine the radius of curvature of a given spherical surface by a spherometer.

7. To determine the mass of two different objects using a beam balance.

8. To find the weight of a given body using the parallelogram law of vectors.

9. Using a simple pendulum, plot L-T and L-T2 graphs. Hence find the effective length of a second’s pendulum using appropriate graph.

10. To study the relationship between the force of limiting friction and normal reaction and to find the coefficient of friction between a block and a horizontal surface.

11. To find the downward force, along an inclined plane, acting on a roller due to the gravitational pull of the earth and study its relationship with the angle of inclination (θ) by plotting graph between force and sin θ.

Section B

1. To determine Young’s modulus of elasticity of the material of a given wire.

2. To find the force constant of a helical spring by plotting a graph between load and extension.

3. To study the variation in volume with pressure for a sample of air at constant temperature by plotting graphs between P and V, and between P and 1/V.

4. To determine the surface tension of water by capillary rise method.

5. To determine the coefficient of viscosity of a given viscous liquid by measuring the terminal velocity of a given spherical body.

6. To study the relationship between the temperature of a hot body and time by plotting a cooling curve.

7. To determine the specific heat capacity of a given (i) solid (ii) liquid, by the method of mixtures.

8. (i) To study the relation between frequency and length of a given wire under constant tension using sonometer.

(ii) To study the relation between the length of a given wire and tension for constant frequency using sonometer.

9. To find the speed of sound in air at room temperature using a resonance tube by two resonance positions.
