1.Force is a: (PMC MDCAT 2022)
- Vector
- Scalar
- Tensor
- Base quantity
Show answer
Correct answer: (a) Vector
Force has both magnitude and direction and adds by the parallelogram rule, so it is a vector.

Vectors and Equilibrium — MDCAT MCQs
2.Displacement is a: (PMC Practice 2021)
- Tensor
- Vector
- Scalar
- None of these options is correct
Show answer
Correct answer: (b) Vector
Displacement has magnitude and direction and adds by the parallelogram rule.
3.Consider these two vectors A = 2i + 3j and B = -6i + 4j. The angle between these two vectors is: (SIBA MDCAT 2025)
- 60°
- 90°
- 120°
- 180°
Show answer
Correct answer: (b) 90°
The scalar product is $-12+12=0$, so the vectors are at right angles.
4.If we double the moment arm the value of torque becomes: (UHS MDCAT 2016)
- Half
- Three-times
- Two-times
- Four-times
Show answer
Correct answer: (c) Two-times
Torque is force times moment arm, so twice the arm is twice the torque.
