Question

A block of iron is kept on a table top of your classroom. the mass of wooden block is 10kg and it's dimensions are 20cm ×20cm× 10cm.find the pressure exerted by the wooden block on the table top when it is kept on the table top as shown in the following figure​

Answer 1

as pressure = force÷area

so we have mass = 10 kg so first we will find force

so

as f=w= mg

as mass = 10

and g also = 10

so . 10 × 10 = 100N
and area =4 × 10 ^-4
so by putting in formula
100÷ 4×10^-4

pressure =250000
