Three particles of each mass ' m ' are kept at the three vertices of an equilateral triangle of side ' 1 '. The moment of inertia of system of the particles about any side of the triangle is

Options

  1. Am l^2 4
  2. Bm l^2
  3. C3 4 m l^2
  4. D2 3 m l^2

Correct answer

C. 3 4 m l^2

Step-by-step solution

The moment of inertia of the system of particle about XX ^ is aligned & I = mx ^2= m (1 60^ )^2 & = 3 4 ml ^2 aligned
