The mass of the first body is 5 times the mass of the second. The support area of the first body is half that of the second. Which body puts a lot of pressure on the table and how many times?

m1 = 5 * m2.

S2 = 2 * S1.

P1 / P2 -?

The pressure of the force P is called a scalar physical quantity, equal to the ratio of the force F to the area S, on which this force acts.

The pressure P is determined by the formula: P = F / S.

The body’s table is acted upon by the force of its weight, the value of which is determined by the formula: F = m * g, where m is the mass of the body, g is the acceleration of gravity.

The pressure of the bodies will be determined by the formulas: P1 = m1 * g / S1, P2 = m2 * g / S2 = m1 * g / 5 * 2 * S1 = m1 * g / 10 * S1 = P1 / 10.

Answer: the pressure of the first body is 10 times higher than the pressure of the second body: 10 * P2 = P1.
