Q1. A resultant force of 12 N acts on an object of mass 4 kg. What is the object's acceleration?

A. 3 m/s²
B. 16 m/s²
C. 48 m/s²
D. 0.33 m/s²

Show answer & explanation

✓ Answer: A. 3 m/s²

Using F = ma, a = F/m = 12/4 = 3 m/s². Multiplying instead of dividing gives the incorrect distractor of 48 m/s².

Q2. A wire of cross-sectional area 2.0 × 10⁻⁶ m² has a tension of 8.0 N applied to it. What is the stress in the wire?

A. 1.6 × 10⁻⁵ Pa
B. 4.0 × 10⁶ Pa
C. 4.0 × 10⁻⁶ Pa
D. 1.6 × 10⁷ Pa

Show answer & explanation

✓ Answer: B. 4.0 × 10⁶ Pa

Stress = force/area = 8.0/(2.0 × 10⁻⁶) = 4.0 × 10⁶ Pa. A frequent mistake is multiplying force and area instead of dividing, which produces an answer with the wrong power of ten and physically meaningless units for stress.

Q3. What condition maximises the power delivered to an external resistor R by a cell of internal resistance r?

A. R must be much greater than r
B. R must be much less than r
C. R must equal r
D. R must equal zero

Show answer & explanation

✓ Answer: C. R must equal r

Maximum power transfer to the external resistor occurs when R = r; at this point half the total power is dissipated internally and half externally. This is a standard result derived by differentiating the power equation with respect to R.
