The coefficient of static friction ₈ , between block A of mass 2 ~kg and the table as shown in the figure is 0.2 . What would be the maximum mass value of block B so that the two blocks do not move? The string and the pulley are assumed to be smooth and massless (g .=10 ~m / s ^2 )

Options

  1. A2.0 ~kg
  2. B4.0 ~kg
  3. C0.2 ~kg
  4. D0.4 ~kg

Correct answer

D. 0.4 ~kg

Step-by-step solution

According to the question T=m_ B q= (m_ A q ) aligned m_ B & = m_ A =0.02 2 & =0.4 ~kg aligned
