Question

A metal box of mass 2.5 kg is kept on a table. The area of contact

of the box and the table is 0.05 m2

. Calculate the force and the

pressure exerted by the box on the table.

​

Answer 1

Explanation:

mass of box = 2.5 kg

accleartion (g) = 9.8 m/s²

area of contact = 0.05 m²

• force = mass × accleartion = 2.5 × 9.8 = 24.5 N
• pressure = force / area = 24.5 / 0.05 = 1.225 pa
