state the laws of friction. te coefficient of static frictin between block A mass=2. and the table is 0.2. what would be the maximum mass of block B so that the two blocks do not move. (the string and the pulley are assumed to be smooth and massless, g=10m/s2)

For block  A,

 friction force  =  Tension in string

 ⇒  µ mg  =  T

 ⇒  0.2 × 2 × 10 =  T

 ⇒  T = 4 N

 For 2nd block,  (B),
