Question

A cylinder of mass 500 g and radius 10 cm has moment of inertia about its central axis in kg-m? equal to (a) 1.25 x 10-3 (b) 2.5 x 10-3 (c) 5.5 x 100 (d) 7.5 x 10-3​

Answer 1

Answer:

b) 2.5 × 10-³

Explanation:

moment of inertia for cylinder at central axis I = MR²/2

I = 500*10*10/2*10000000

  = 2.5 * 10-3
