Question

the pressure of thousand Pascal act on surface area 15 CM square by a block of mass M calculate M calculate the new pressure exerted by the same block if the area of contact with the surface become 10 cm square

Answer 1

force = pressure*area

F = 1000*15/10000 = 1.5 N

force = mg

1.5 = m*10

so m = 0.15 kg  or 150 gm

new p = f/a

p = 1.5/10 * 10000

P = 1500 N
