⑴如图甲，在弹簧的下端挂一个小桶，小桶的下面吊一个石块，记下弹簧伸长后下端到达的位置O，将此时弹簧对小桶的拉力计为T₁，小桶与石块的总重记为G，则T₁ ____G（选填“＞”“＜”“=”）；

⑵如图乙，在溢水杯中盛满水，当石块浸没在水中时，排出的水便流到旁边的小水杯中，将排出的水的重力记为G_排；

⑶如图丙所示，把小杯中的水全部倒入弹簧下方的小桶中，弹簧的下端又会到达原来的位置O，将此时弹簧对小桶的拉力记为T₂，则T_{2____}T₁（选填“＞”“＜”“=”）；

⑷通过对图丙中小桶和石块的受力分析，请推导石块受到的浮力F_浮与排出水的重力G_排之间的关系____。（要求写出推导过程）
