MDCAT Physics MCQ #1842

  1. Question 1

    Q1. The terminal velocity of a sphere falling in a viscous fluid is directly proportional to

    • A) The square of its radius
    • B) The square of its density
    • C) The fluid's viscosity
    • D) The gravitational acceleration

    Answer: The square of its radius

    Explanation: Terminal velocity is proportional to the square of the sphere's radius according to Stokes' law. Option C is incorrect because terminal velocity is inversely proportional to viscosity.
