Question

A box of 500N is kept on a table. Find the pressure exerted by it on the table if the surface area of contact is 100 cm².
I) 5000 pa
ii) 50000 pa
iii) 5000 N
iv) 100 N​

Answer 1

Answer:

ii) 50000 pa.

Explanation:

Weight of a box = 500N

Surface area of contact = 100 cm²

Pressure exerted by it on the table = 500 × 100

= 50000 pa.

I hope you understand this answer to you.

Answer 2

Given : A box of 500N is kept on a table.

To Find : the pressure exerted by it on the table, if the surface area of contact is 100 cm²

I) 5000 pa

ii) 50000 pa

iii) 5000 N

iv) 100 N​

Solution:

Pressure = Force / Area

Force = 500 N

Area = 100 cm²  = 100 / 10000  m²

= 1/100 m²

Pressure = 500 / (1/100)

=> Pressure = 50000  N/m²

=> Pressure = 50000  Pascal

50000  Pa is correct option
