A T shaped uniform density object with dimensions shown in the figure is lying on a smooth floor. A force F → is applied at the point P parallel to AB such that the object has only the translational motion without rotation. Find the location of P with respect to C .

Options

  1. A4 3 l
  2. Bl
  3. C3 4 l
  4. D3 2 l

Correct answer

A. 4 3 l

Step-by-step solution

It is a case of translation motion without rotation. The force should act at the centre of mass Y cm = m × 2 l + 2 m × l m + 2 m = 4 l 3 ( considering point C as origin )
