Question

A cement block of weight 100N has sizes of length 10cm, 20cm, and 24cm. What is the pressure exerted by the block when it is lying on the side with the greater area?

a) 0.25 Pa
b) 0.50 Pa
c) 1.00 Pa
d) 2.00 Pa

Answer 1

The pressure exerted by the cement block when lying on the side with the greater area is 2.00 Pa.

Step-by-step explanation:

The pressure exerted by the cement block can be calculated using the formula:

Pressure = Force / Area

Since the weight of the block is given as 100N, and the side with the greater area is not specified, we will assume that it refers to the largest face of the block which has dimensions of 20cm x 24cm = 480cm² = 0.048m². Therefore, the pressure exerted by the block is:

Pressure = 100N / 0.048m² = 2083.33 Pa

So the correct option is d) 2.00 Pa.
