## Sample NECO 2024 Physics Practical Questions and Answers

### Question 1: Determination of the Acceleration Due to Gravity Using a Simple Pendulum

**Apparatus:**

- A simple pendulum (string and bob)
- Stopwatch
- Meter rule
- Retort stand

**Procedure:**

- Set up the simple pendulum by suspending the bob from a fixed point with the string of length, L.
- Measure the length, L, of the pendulum from the point of suspension to the center of the bob using a meter rule.
- Displace the bob slightly and release it to swing freely.
- Use the stopwatch to measure the time, t, for 20 complete oscillations.
- Record the time and repeat the measurement two more times to get the average time.
- Calculate the period, T, of one oscillation (T = t / 20).
- Repeat the experiment for different lengths, L, of the pendulum (e.g., 40 cm, 50 cm, 60 cm, 70 cm, 80 cm).

**Data Table:**

Length (L) | Time for 20 Oscillations (t) | Period (T = t/20) |
---|---|---|

40 cm | … | … |

50 cm | … | … |

60 cm | … | … |

70 cm | … | … |

80 cm | … | … |

**Calculation:**

- Calculate the square of the period, T^2, for each length, L.
- Plot a graph of L (y-axis) against T^2 (x-axis).

**Formula:** $T=2πgL $ $T_{2}=(2π)_{2}gL $ $L=πg T_{2}$

From the slope of the graph (L/T^2), determine the acceleration due to gravity, g.

### Question 2: Verification of Ohm’s Law

**Apparatus:**

- Resistor
- Ammeter
- Voltmeter
- Power supply
- Rheostat
- Connecting wires
- Switch

**Procedure:**

- Connect the circuit as shown in the diagram below:(Include a simple circuit diagram showing a resistor, ammeter in series, voltmeter across the resistor, power supply, and rheostat.)
- Close the switch and adjust the rheostat to obtain different readings of current, I, through the resistor.
- For each current reading, record the corresponding voltage, V, across the resistor using the voltmeter.
- Repeat the measurements for at least five different current values.
- Record the data in a table.

**Data Table:**

Current (I) | Voltage (V) |
---|---|

… | … |

… | … |

… | … |

… | … |

… | … |

**Calculation:**

- Plot a graph of V (y-axis) against I (x-axis).
- Determine the slope of the graph, which represents the resistance, R, of the resistor.

**Conclusion:** Ohm’s Law states that $V=IR$, hence the straight-line graph through the origin confirms the law, with the slope equal to the resistance.

### Question 3: Determination of the Focal Length of a Converging Lens

**Apparatus:**

- Converging lens
- Lens holder
- Screen
- Meter rule
- Light source (e.g., candle or lamp)

**Procedure:**

- Set up the apparatus as shown in the diagram below:(Include a simple setup diagram showing the lens, screen, and light source.)
- Place the lens in the holder and position it at a known distance from the light source.
- Move the screen until a sharp image of the light source is formed on the screen.
- Measure the distance between the lens and the screen; this is the image distance (v).
- Measure the distance between the light source and the lens; this is the object distance (u).
- Record the values of u and v for different positions of the lens.

**Data Table:**

Object Distance (u) | Image Distance (v) | 1/u (1/m) | 1/v (1/m) |
---|---|---|---|

… | … | … | … |

… | … | … | … |

… | … | … | … |

**Calculation:**

- Use the lens formula: $f1 =u1 +v1 $.
- Calculate the focal length, f, for each pair of u and v values.
- Find the average focal length of the lens.

**Conclusion:** The average focal length of the lens is determined using the lens formula and the recorded measurements.
