The coefficient of static friction 
, between block 
of mass 2 kg and the table as shown in the figure 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 (take, 
).
Text Solution
Verified by ExpertsThe correct answer is:
D
Let the mass of the block 
is 
.
In equilibrium, 
…(i)
If blocks do not move, then
for limiting case, 
…(ii)
Thus, from Eqs. (i) and (ii), we have
