Question

what will be the pressure when a 30 N force is applied on an area of 120 cm square ​

Answer 1

$we \: know \: that \\ p = \frac{f }{a} \\ \\ here \\ force \: f \: = 30 \: n \\ surface \: area \: = 120cm {}^{2} \\ \\ according \: to \: the \: formula \\ \\ p \: = \frac{30}{120} \\ \\ hence \\ pressure \: = 40 \: pascal$
