A hollow tilted cylindrical vessel of negligible mass rests on a horizontal plane as known. The diameter of the base is a and the side of the cylinder makes an angle with the horizontal. Water is then slowly poured into the cylinder. The cylinder topples over when the water reaches a certain height h , given by.

Options

  1. Ah=2 a
  2. Bh=a ²
  3. Ch=a
  4. Dh= a 2

Correct answer

C. h=a

Step-by-step solution

= h 2 a / 2 ~h = a
