A diver descends from the surface of a lake to a depth of 15 m. The density of the water is 1000 kg/m³ and g = 10 N/kg. What is the increase in pressure on the diver due to the water?

Q: How do I try a free CIE Physics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Physics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Physics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Physics questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Physics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Accepted Answer

150 000 Pa — Award 1 mark for correct calculation: p = ρgh = 1000 × 10 × 15 = 150 000 Pa. A is incorrect — this divides by 100 (error in powers of 10). B is incorrect — this omits one factor (likely gravity). D is incorrect — this incorrectly multiplies by an extra factor of 10.
