Question

a force of 300 Newton acts on a surface of area 10 centimetres square calculate thrust and pressure calculate change in pressure if the area increases to 15 centimetre square???

Answer 1

thrust=force=200N
p1=f/a1
where a1=o.oo1msq
p1=200N/o.oo1msq
  =200000pa

p2=f/a2
where a2=o.005msq
p2=200N/0.oo5 msq
    = 40000pa

Answer 2

Hi there !!

Force = 300 N

Area = 10 cm² = 0.001 m²

Thrust = Force = 300 N

Pressure = Thrust / Area

= 300/0.001
= 300000 Pa

================================

Area = 15 cm² = 0.0015 m²

Thrust = 300 N

Pressure = Thrust / Area
= 300/0.0015
= 200000 Pa
