    3751.34N

    Explanation:

    Pressure in large piston = pressure in smaller piston

    P2 = P1

    Pressure = Force / Area

    Area = pi * r²

    r1 = d1/2 = 10 / 2 = 5cm = 0.05m

    Area (A1) = 22/7 * (0.05) ² = 0.00785m²

    r2 = d2 / 2 = 25/2 = 12.5cm = 0.125m

    Area (A2) = 22/7 * (0.125) ² = 0.04908m²

    Pressure = Force / Area

    F1/A1 = F2/A2

    600 / 0.00785 = F2 / 0.04908

    F2 = (600 * 0.04908) / 0.00785

    F2 = 3751.34N

    3750 N

    Explanation:

    Pressure on the small cylinder = pressure on the large cylinder

    P₁ = P₂

    F₁ / A₁ = F₂ / A₂

    F₁ / (π d₁² / 4) = F₂ / (π d₂² / 4)

    F₁ / d₁² = F₂ / d₂²

    600 N / (10.0 cm) ² = F / (25.0 cm) ²

    F = 3750 N
