Q6. What will be the pressure when 30 N force applied on 120 cm2 area?
(a) 2.5 × 103 N/m2
(b) 2.5 × 104 N/m2
(c) 2.5 × 102 N/m2
(d) 5 × 103 N/m2
Dear student,Force applied=30NArea=120cm^2=120x10^-4m^2We know that, Pressure=Force/AreaPressure=30/120x10^-4m^2Pressure=0.25x10^4N/m^2=2.5x10^3N/m^2So, the correct answer is (a).Regards
