✍️ Sample Competency-Based Questions

🔹 Maths Example

Q: A ladder is placed against a wall making an angle of 60° with the ground. If the length of the ladder is 20 m, find the height it reaches on the wall.

Solution:
$\sin 60° = \frac{\text{height}}{20}$
$\text{height} = 20 × \frac{\sqrt{3}}{2} = 10\sqrt{3} ≈ 17.32 m$

👉 Quick Tip: Always draw a right triangle first to avoid silly mistakes in trigonometry.

🔹 Science Example

Q: Why do iron filings form distinct patterns around a bar magnet? What does this indicate?

Solution:
Iron filings align along the magnetic field lines of the magnet.
This shows the direction and shape of the magnetic field, which is invisible but represented by the alignment of filings.

👉 Common Mistake: Writing “magnetic force” without explaining field line pattern.
