A circular disc is to be made by using iron and aluminium, so that it aquires momentum of inertia about its geometrical axis. It is possible with

Options

  1. Airon and aluminium layers in alternate order
  2. Baluminium at interior and iron surrounding it
  3. Ciron at interior and aluminium surrounding it
  4. DEither (a) or (c)

Correct answer

B. aluminium at interior and iron surrounding it

Step-by-step solution

By doing so the distribution of mass can be made away from the axis of rotation.
