Hey dear,
◆ Answer-
m2 = 3.75 kg
◆ Explaination-
# Given-
r1/r2 = 20/1
m1 = 1500 kg
# Solution-
As both pistons are in synchrony, thrust applied will be equal.
P1 = P2
F1 / F2 = A1 / A2
We know, F = mg & A = πr^2 ,
m1g / m2g = πr1^2 / πr2^2
m2 = m1 (r2/r1)^2
m2 = 1500 × (1/20)^2
m2 = 3.75 kg
Mass applied on small piston is 3.75 kg
Hope this helps you...
