If you look at it from the frame of reference of the liquid, what will happen, the value of g will get replaced by g'

So the bouyant force will be B0 x g'g where B0 was the initial bouyant force.

In the same way, The weight of the body will be W0 x g'g

Since for floating weight of liquid dispalced is equal to the weight of the solid... therefore,

The height will not change at all.....
