Question

A uniform cube of edge length 5 cm and and mass 5 kg kept on a tabletop. Find the pressure due to the cube on the table top on the portion where the cube touches the table top.

Answer 1

Mass- (10×5)= 50N. (g=10m/s)
P=F/A
50/5÷100×5÷100
50/25×10000
2×10to the power 4 N/M square

Answer 2

Answer:

edge =5cm

=5/100 =0.05

m = 5kg

p=?

p=f/a

=mg/(edge)^2

p= 5×9.8/(0.05)^2

=5×9.8×10000/0.05×0.05

5×98×1000/ 25

=5×98×40

=19600 n/m^2
