A block of mass m is placed on a smooth inclined wedge A B C of inclination as shown in the figure. The wedge is given an acceleration 'a' towards the right. The relation between a and for the block to remain stationary on the wedge is

Options

  1. Aa= g cosec
  2. Ba= g
  3. Ca=g
  4. Da=g

Correct answer

C. a=g

Step-by-step solution

Let the mass of block is m. It will remains stationary if forces acting on it are in equilibrium. i.e., m a =m g a=g Here ma = Pseudo force on block, mg = weight
