1.	2)A force of 20 N acts over a surface having an area 4cm2.What is the pressure on this surface?
Answer» Answer: Pressure = FAFA F = 20 N A = 4 CM2 = 4 X 10-2 m P = FAFA = 2040×10−22040×10−2 = 5 x 102 = 500 Nm-2 (or) 500 pack

Answer:

Pressure = FAFA F = 20 N A = 4 CM2 = 4 X 10-2 m P = FAFA = 2040×10−22040×10−2 = 5 x 102 = 500 Nm-2 (or) 500 pack
