Summary

• Description:

  The MS Word document comprises MINCKS Group of Schools Physics Paper 3 (Practical) Pre-Mock 2022 Exam with Answers (Marking Scheme). The PDF version is also available upon your request. The marking scheme is in a different document.

  It was a MINCKS Group of Schools Form Four examination.

  This practical Physics paper evaluates a student's hands-on experimental skills, focusing on electricity, optics, and fluid mechanics. It tests their ability to assemble apparatus, record accurate data, plot graphs, and derive physical constants.

  • Duration: 2.5 Hours
  • Total Marks: 40
  • Structure: Question 1 (Electricity) and Question 2 (Optics & Mechanics)

  It covers the following topics:

  • Question 1: Electricity
    • Setting up circuits to measure electromotive force (E) and potential difference (V)
    • Calculating resistance using Voltmeter and Ammeter readings
    • Using a Wheatstone bridge/potentiometer setup with a galvanometer to find balance points
    • Investigating the effective resistance of resistors in series
    • Plotting and analyzing a graph of inverse balance length (1/a) against inverse resistance (1/X) to determine specific circuit constants
  • Question 2: Optics and Mechanics
    • Part A (Optics): Using a water-filled beaker as a cylindrical lens
    • Calculating the internal radius of a beaker based on water volume and height
    • Determining object (candle) and image distances to find the focal properties of the water lens
    • Part B (Mechanics): Using vernier calipers and micrometer screw gauges
    • Determining the volume of ball bearings and the cross-sectional area of a test tube
    • Investigating buoyancy and the principle of flotation by adding mass (ball bearings) to a floating test tube
    • Calculating the ratio of the density of steel to the density of water based on displacement data
