Physics equation, don't understand completely

I have this equation from Fluids/elasticity of solids...

where p is the density (rho)

p(object) < p(fluid) ----> weight(object) = F(buoy)

This is from TPR hyperlearning. I understand that if the object density if less than the fluid it will float. I'm not sure what "the arrow pointing to the weight and then = to the buoyant force" means.

Is this stating the buoyant force is equal to the weight?

Apparent weight = weight minus buoyant force.

W(a) = w - F

I guess I just am not making sense out of the second part of this equation:
p(object) < p(fluid) ----> weight(object) = F(buoy)

thx in advance.😍

Here's what they're referencing. It's important. If an object floats, then in order for it to float, the force buount must balance the force due to gravity. An object can only float if it's density is less than the fluid or if it's on a piece of foam.

po < pwater So Mg=po*V*g =pw*Vd*g
Now, note that because po is less than pw, that the volume of water displaced is less than the Volume of the object itself. When an object floats, IT DISPLACES ITS WEIGHT.

Apparent weight in this case is 0!!! Since it is floating, M(a)=0=W- Fb
W=Fb

When an object is submerged, IT DISPLACES IT'S OWN VOLUME OF WATER. So the b force isn't as much.

Once again, when an object floats, Apparent weight in this case is 0!!! This IS NOT the case when it is submerged which is why you were confused. What you did applies in that case.
