Question

A uniform beam (M=10 kg, L=4 m) is supported at one end. Force required at other end to keep it horizontal (g=10 m/s²):
  1. A
    100 N
  2. B
    50 N
    Correct
  3. C
    25 N
  4. D
    200 N

Correct answer

50 N

Explanation

Taking support as pivot: F×L = Mg×L/2. F = Mg/2 = 10×10/2 = 50 N.
