Question 1 · 1 mark · Difficulty 1/3

Which of the following correctly states Coulomb's Law?

  1. A. The force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.
  2. B. The force between two charges is proportional to the sum of the charges and inversely proportional to the distance between them.
  3. C. The force between two charges is proportional to the product of the charges and inversely proportional to the distance between them.
  4. D. The force between two charges is proportional to the square of the charges and inversely proportional to the square of the distance between them.
Show answer & explanation
✓ Answer: A — A. The force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.
Coulomb's Law states that the electrostatic force F = kQ₁Q₂/r², meaning force is proportional to the product of the two charges and inversely proportional to the square of the separation distance. Options B, C, and D incorrectly modify either the charge relationship or the distance relationship.
Question 2 · 1 mark · Difficulty 1/3

A positive test charge is placed in a uniform electric field. Which of the following correctly describes the direction of the electric force on the test charge?

  1. A. Opposite to the direction of the electric field.
  2. B. Perpendicular to the direction of the electric field.
  3. C. In the same direction as the electric field.
  4. D. At 45° to the direction of the electric field.
Show answer & explanation
✓ Answer: C — C. In the same direction as the electric field.
By definition, the electric field direction at any point is the direction of the force on a positive test charge placed at that point. Therefore, a positive charge experiences a force in the same direction as the field.

CXC CSEC Physics: Electric Fields and Coulomb's Law FAQ

How many CXC CSEC Physics questions on Electric Fields and Coulomb's Law are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Electric Fields and Coulomb's Law for CXC CSEC Physics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Physics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Electric Fields and Coulomb's Law practice with other Physics topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Electric Fields and Coulomb's Law questions aligned to the official CXC CSEC Physics syllabus?
Every question is written against the published CXC CSEC Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Electric Fields and Coulomb's Law typically tested on CXC CSEC Physics papers?
Electric Fields and Coulomb's Law appears across multiple question types on real CXC CSEC Physics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
