Question

7

If 100 N force is applied normally on a table top whose length is 4 m & breadth is 5 m then the pressure acting on the table top will be-

(A)   5 N/m2

(B)   10N/ m2

(C)   5 N/ m

(D)   None of these​

Answer 1

Answer:

none of these

Explanation:

Given, froce=100N

and area=4m

2

∴pressure=

area

force

=

4m

100N

=25Pa

Answer 2

Answer:

A)

Explanation:

area of rectangle = l × b = 20m^2

pressure = force / area

p = 100 / 20

p= 5 N/m2
