The centre of mass of a homogenous semi-circular plate of radius r is located at A as shown in the figure. The distance OA is

Options

  1. A2r 3
  2. B4 r 3
  3. C3r 2
  4. Dr

Correct answer

B. 4 r 3

Step-by-step solution

The COM of a homogeneous semi-circular plate is located at 4 r 3 distance from ' O '. So, O A= 4 r 3
