```							Ok watch

mass of block=50kg
coeff.of static friction=0.5
Tking vertical axis,
N-mg=0(since no motion in vertical direction)
or n=mg
therefore,maximum static friction=Coeff.of friction*Normal reaction
=0.5*mg
=0.5*50*10                                     =250 Newtons
If the boy applies force equal to 250N,the block would tend to move
