Vector Addition
1. The unit which is based on one or more base units is called
- A. SI Unit
- B. Derived unit
- C. Unit vector
- D. Base unit
View answer and explanation
Answer: B. Derived unit
SI base units are the seven fundamental units such as metre, kilogram and second, while any unit formed by combining them, like the newton (kg m/s²) or joule, is a derived unit. A unit vector is a direction vector of magnitude one, not a system of units. So a unit built from one or more base units is a derived unit.
Vector Product
2. The direction of the cross product of and is given by:
- A. Left-hand rule
- B. Right-hand rule
- C. Fleming's rule
- D. Newton's rule
View answer and explanation
Answer: B. Right-hand rule
convention, the direction of A x B is found with the right-hand rule: fingers curl from A toward B and the thumb points along A x B. The left-hand rule is not used for this, and Fleming's rule applies to motors and generators. So the right-hand rule is correct.
Vector Addition
3. The direction of torque, defined as = r x F, is found using the:
- A. Head-to-tail rule
- B. Right-hand rule
- C. Pythagorean theorem
- D. Left-hand rule
View answer and explanation
Answer: B. Right-hand rule
The direction of the vector product is determined by the right-hand rule, where rotating the fingers from the first vector to the second gives the direction of the thumb as the resultant.

Common questions about Vectors and Equilibrium practice
How many Vectors and Equilibrium MCQs are available on DIFF. MDCAT?
The current Vectors and Equilibrium question bank contains 674 practice MCQs across 4 topics. This is the bank size, not the length of one test. Choose your topics and a question count from 1 to 180, limited by the questions available in those topics.
Which topics does the Vectors and Equilibrium quiz cover?
The selectable topics are Vector Addition, Scalar Product, Vector Product, Equilibrium. Use Select all for a broad chapter drill, Clear to start a focused selection, or choose individual topics. Questions are drawn from your chosen topics, so you can target a weak concept before returning to a wider test.
How do I build a custom Vectors and Equilibrium test?
Open the chapter builder, select one or more topics, enter your question count, and choose Tutor Mode or Timed Exam. The available-question total updates with your selection. Start Test generates a shuffled drill; you do not have to follow a fixed Quiz 1 or Quiz 2 sequence.
What is the difference between Tutor Mode and Timed Exam?
Tutor Mode gives feedback and an explanation after you choose an option, and you can change or clear that choice. Timed Exam runs a countdown and keeps explanations hidden until submission. Both modes let you move between questions, use the paper map, and submit for a complete review.
How do I review and download my Vectors and Equilibrium quiz?
Select Submit Quiz, then Submit & View Explanations. The review includes every question in your test, all options, your selection, the marked correct answer when a key is available, and the explanation. Download PDF saves a paginated review; Download Review saves an HTML copy you can open in a browser. The review also includes DIFF. MDCAT community links.
How should I use Vectors and Equilibrium MCQs to improve?
Start with a short tutor drill on one of these topics: Vector Addition, Scalar Product, Vector Product. Read the explanation for incorrect and uncertain answers, revise the relevant textbook section, and retry before taking a timed drill. Compare your reasoning with the answer key rather than memorising the option letter.
