Question

A force of 50 kgf is applied to the smaller piston of area 20 cm2 to balance a force of 2000 kgf on larger piston. Find the area of larger piston.

Answer 1

800 cm2

mark me as brainliest

Answer 2

Area of the larger piston = 800 sq. cm.

Explanation:

Pressure = Force / area

In a piston, we know that Force (smaller piston) / area of smaller piston = Force larger piston) /  area of larger piston

So we get, 50 / 20 = 2000 / x

Solving for x = 2000 * 20 / 50 = 40 * 20 = 800 sq. cm

Area of the larger piston = 800 sq. cm.
