Question

A women based 2000 N . The area of her feet is 200 cm square. How much pressure does she exert on the ground when she stands on both her feet and when she stands on just one foot?

1. 400000 pa and 50000 pa
2. 100000 pa and 200,000 pa
3. 600000 pa and 700000 pa​

Answer 1

Answer:

100,000 pa and 200,000 pa

Explanation:

Pressure = force ÷ area

P = 2000 N ÷ 2.00 metres

P= 1000 x 200

Pressure of both feet = 200,000 pa

Pressure of 1 foot = 200,000 ÷ 2

                             =  100,000 pa

Answer 2

Explanation:

Pressure =Force÷Area

P=2000N÷2.00meters

P=1000×200

Pressure of both feet=200,000pa

Pressure of 1 foot=200,000÷2

=100,000pa
