Question

A rectangular block has the dimensions of 10 x 5cm and occupies a weight of 20 g. Calculate the pressure

Answer 1

Answer:

Pressure= Force/Area

Area of a rectangle= l*b= 10*5= 50$cm^2$

If weight= Force/Gravity

Force=Weight/Gravity

Force=20g/100Ng

Force=0.2N

Pressure=0.2N/50$cm^2$

Pressure= 0.004Pa
