A force of 16 N is distributed uniformly on one surface of a cube of edge 8 cm. The pressure on this surface is:

Options

A. 3500 Pa
B. 2500 Pa
C. 4500 Pa
D. 5500 Pa

Answer

B

Explanation

Here, Force acting on the surface, F = 16 N
Area of the surface on which this force acts,
`A = 8 cm xx 8 cm = 64 cm^2 = 64 xx 10^(-4) m^2`
The pressure on the surface is P` = F/A = (16N )/(64 xx 10^(-4) m^2) = 2500 Pa`
