MDCAT Physics MCQ #1824

  1. Question 1

    Q1. If a force of 10 N is required to move a 2 m² plate at 5 m/s over a 1 m thick liquid layer, what is the viscosity?

    • A) 1.0 Ns/m²
    • B) 1.0 Nm/s
    • C) 1.0 J/m²
    • D) 1.0 kg/ms²

    Answer: 1.0 Ns/m²

    Explanation: Viscosity is defined as η = (Force * distance) / (Area * velocity). Using units: (N * m) / (m² * m/s) = Ns/m². Option C is power.
