  • Duration: 2hrs 30 Mins
  • Total Marks: 40
  • Structure: Two main practical questions.

  It covers the following topics:

  • Question 1: Measurement and Electricity
    • Part A: Measuring the dimensions (height, diameter) and mass of a dry cell using Vernier calipers and a weighing balance to determine a constant.
    • Part B: Setting up a circuit with a Nichrome wire on a metre rule. Measuring voltage and current across varying lengths of the wire. Plotting a graph of resistance against length to determine the resistivity (constant K) of the wire.
  • Question 2: Mechanics and Optics
    • Part A (Mechanics): Using the principle of moments to determine the upthrust force and the density of an unknown liquid by balancing a metre rule with a submerged mass.
    • Part B (Optics): Determining the focal length and power of a convex lens using the no-parallax method with pins mounted on a metre rule.
