Question

how much pressure exerted by Ruhi on a surface with a pencil shoe with area 0.5 mm square if ruhi weighs 50kg.​

Answer 1

Answer:

pressure=force /area=mg/area

• here
• m=50kg
• g=9.8m/s^2
• area=0.5mm^2=(0.5/1000)^2 m^2 =0.5×10^-6 m^2

pressure

$\frac{50 \times 9.8}{0.5 \times 10 {}^{ - 6} } newton.m {}^{ - 2} \\ = 980 \times 10 {}^{6} \\ = 9.8 \times 10 {}^{8} \: \: pascal$
