Question

A girl weighing 50 kgf wears sandals of dimensions 1.5 cm x 1 cm. Find the pressure exerted on the ground.​

Answer 1

GIVEN

• Weight of girl = 50kgf
• length of sandal = 1.5 cm
• Breadth of sandals = 1 cm

SOLUTION

• We know that
• 1 kgf = 9.81 N
• 50 kgf = 9.81×50 = 490.5 N
• Length = 1.5 cm = 0.015 m
• Breadth = 1 cm = 0.01 m

• Presure = Force / Area

• Area = Length × Breadth
• Area = 0.015 × 0.01
• Area = 0.00015 m²

• Presure = Force / Area
• Presure = 490.5 / 0.00015
• Presure = 3270000 N/m² or Pascal
• Presure = 327 N/cm²

Answer 2

Answer:

327N/cm ² is the answer ...
