Two cubes of masses 3 g and 6 g and sides of
length 2 cm and 3 cm respectively are placed on
a smooth table as shown in the figure. Calculate
the pressure experienced by the table due to the
system of boxes. [Take g = 10 m/s2]

Answer:
Force (F1) of cube 1 = Mass*Acceleration = 3*10 = 30 N
Force (F2) of cube 2 = 6*10 = 60 N
Area (A1) of cube 1 = S*S = 2*2 = 4 cm^2
Area (A2) of cube 2 = S*S = 3*3 = 9 cm^2
Total pressure (P) = (F1/A1) + (F2/A2)
P = (30/4) + (60/9) = 7.5 + 6.7
P = 14.2 Pascal
