Question

Who will exert more pressure a girl of a mass 500 kg wearing sandals each of area 10cm.^2 or an elephant in a circus of mass 250 kg standing on a single foot of area 25cm.^2

Answer 1

weight of girl = 500×10 = 5000N
pressure exerted by the girl = 5000÷0.002 = 2500000Pa

weight of elephant = 250×10 = 2500N
pressure exerted by the elephant = 2500÷0.0025 = 1000000Pa

Therefore, since the pressure exerted by the girl is more than the pressure exerted by the elephant, the elephant will exert more pressure.

Hope this helps!
