2024 Neco Physics Practical | Expo Questions and Answers

  (1ai -1aiv) S/N|M(g)|Real values of b(cm)|Converted values of b(cm)| Real Value of d(cm)| Converted values of d(cm)| N = b/d 1 |20 |5.30|26.50|12.9|64.5|0.41| 2 |40 |8.0 |40.0 |10 |50.0|0.80| 3 |60 |9.9 |49.5 |8.3|41.5|1.20| 4 |80 |11.0|55.0 |7.0|35.0|1.50| 5 |100|12.1|60.5 |6.0|30.0|2.0| (1av) {PLOT THE GRAPH} (1avi) Slope = Y2-Y1/X2-X1 =70-20/1.4-0.4 = 50/1 =50g (1avii) (i) I avoid error due to parallel when taking all my reading (ii) I made sure that the meter rule be connect horizontally before taking my reading (1bi) (i) The total upward force must balance the downward. (ii) The algebraic sum of all forces act on the body must be equal to zero. (1bii) The sum of clockwise moment = the sum of anti clockwise moment. 20 × (50-5) = 100 × (x-50) 20 × 45 = 100(x-50) 900 = 100x – 5000 900 + 5000 = 100x 5000/100 = 100x/100 x = 59cm :. The distance from the balance point is 59-50 = 9cm. :. 100g mass is 9cm from the balance point. (3ai -3aiv) S/N|R(ohms)|V(v)|I(A)|1/v(A/v)|R-¹(ohm-¹)| 1 | 1.0|1.21|1.80|1.49|1.00 2 | 2.0|1.50|1.50|1.00|0.50 3 | 3.0|1.64|1.36|0.83|0.33 4 | 4.0|1.72|1.29|0.75|0.25 5 | 5.0|1.76|1.23|0.70|0.20 (3av) PLOT THE GRAPH (3avi) Slope = ΔA/V / ΔR-¹ = 1.28 – 0.80/ 0.80 – 0.30 = 0.48/0.50 = 0.96 Intercept (c) = 0.50 (3avii) (i) I would ensure I made tight connection before taking my reading. (ii) I would ensure I noted zero error on the voltmeter and Ammeter (3bi) Potential difference is the work done in moving a unit charge from a point in electric field to another. It has the unit of Volt. V = work done/charge (3bii) r = 0.5ohms I = 1.2A R = ? E = 3v E = I(R+r) E = IR + Ir E – Ir = IR R = E – Ir/I = 3 – 1.2 × 0.5/1 .2 = 3 – 0.6/1.2 R = 2.4/1.2 R = 2 ohms
