Question

a glass slab has dimension 8cm x 5cm x 4cm. if density of glass is 2.5x10 3 kg/m3 ,the pressure exerted by the glass slab when it rests on surface 5cm x 4cm is: (g=10m/s2)

1. 0.8 pa

2. 8.0 pa

3. 2000 pa

4. 2 x 105

Answer 1

hiiii friend
here is your answer
$pressure = h \times d \times g \\ = \frac{8}{100} \times 2.5 \times {10}^{3} \times 10 \\ = 8 \times 2.5 \times 100 \\ = 20 \times 100 \\ = 2000pa$



glad to help you
hope it helps
thank you.
