MDCAT Physics MCQ #3682

  1. Question 1

    Q1. A 100 N weight is hung from the middle of a light string, making an angle of 30 degrees with the horizontal. Calculate the tension.

    • A) 100 N
    • B) 50 N
    • C) 200 N
    • D) 86.6 N

    Answer: 100 N

    Explanation: In vertical symmetry, 2T sin(theta) = W. Here T = 100 / (2 * sin 30) = 100 N. Option B ignores the vertical component factor.
