Answer 2

★ Given :

• → A block of iron of mass 7.5 kg and of dimension 12 cm x 8 cm x 10 cm is kept on a table top on its base of side 12 cm x 8cm.

★ To Find :

• → Calculate thrust and pressure on table top.

★ Formula Used Here :

• → Thrust = Force
• → Thrust = mg
• → Pressure = Thrust / Area

❍ According to Question :

• → Thrust = mg
• → Thrust = 7.5 × 10
• → Thrust = 75 Newton

❍ Calculating Pressure :

• → Pressure = Thrust / Area
• → Pressure = 75 / 0.0096
• → Pressure = 7812.5 Pascal

★ Therefore :

• → Thrust on table top is 75 Newton
• → Pressure on table top is 7812.5 Pascal
