Question

Mihir and Varun have surface area of their palms as 0.15m^2 and 0.25m^2 .How much force they need to apply so that pressure on their palms is 2000Pa?

Answer 1

Surface area of Mihir's palm = 0.15 m²

Surface area of Varun's palm = 0.25 m²

Pressure = 2000 Pa

So,

Pressure = Force/Area

In case of Mihir,

2000 = F/0.15

=> F = 2000 × 0.15 = 300 N

In case of Varun ,

2000 = F/0.25

=> F = 2000 × 0.25 = 500 N
