  • Month Administered: June 2026
  • Duration: 2½ Hours
  • Total Marks: 40
  • Structure: Two compulsory practical questions, each carrying 20 marks.

  It covers the following topics:

  • Experimental Optics
    • Determination of focal length using a distant object
    • Convex lenses
    • Combined lenses
    • Formation of sharp, inverted images
    • Measurement of object and image distances
    • Graphical determination of constants
  • Elasticity and Springs
    • Extension of a spring
    • Effect of volume of liquid on extension
    • Experimental determination of density
    • Use of a metre rule and spring-pointer system
  • Electrical Measurements
    • Current and potential difference
    • Resistance of a wire
    • Measurement of wire diameter using a micrometer screw gauge
    • Cross-sectional area
    • Resistivity of constantan and copper wires
    • Comparison of resistivities
  • Resistance and Ohm's Law
    • Potential difference-current measurements
    • Resistance calculations
    • Mean resistance
    • Experimental data tables
    • Graphical analysis

  The practical paper requires candidates to make actual observations and measurements, record experimental data in tables, calculate derived quantities and use graphs to determine physical constants. The apparatus includes lenses, metre rules, springs, measuring cylinders, ammeters, voltmeters, galvanometers, a micrometer screw gauge, constantan and copper wires, cells and connecting wires. The apparatus and experimental arrangement are specified on pages 2–8 of the paper. :chatgpt-content-reference{index="4"}
