Answer 1

Answer:

0.5  KgF cm⁻², 0.5  KgF cm⁻², 160 KgF

Explanation:

(1) mass M= 4 Kg

Force F = 4×1 KgF = 4 KgF

Now, Pressure P = F/A = 4/8  KgF cm⁻² = 0.5  KgF cm⁻²

(2) According to Pascal law, a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.

So, prressure in B = prressure in B = 0.5  KgF cm⁻²

(3) P = F/A

►F = PA = (0.5×320) KgF = 160 KgF
