A heavy plate is held horizontal resting on two frictionless pistons, each of which is placed in the opening of an asymmetric U tube filled with an incompressible fluid, as shown in the figure. Once the restraints on the plate are released, then
a) piston A₁ will rise and A₂ will fall;
b) piston A₂ will rise and A₁ will fall;
c) the plate will remain level and not move;
d) the plate will remain level and both pistons will sink a similar small distance.
