Expert Answer:

The attraction force of two 1 kg mass objects which lie at 1 m distance is called Gravitational constant.
 
begin mathsize 12px style straight F equals fraction numerator Gm subscript 1 straight m subscript 2 over denominator straight r squared end fraction
because straight m subscript 1 equals straight m subscript 2 equals 1 space kg space and space straight r equals 1 space straight m
therefore straight F equals straight G end style
 
Ice floats on water because its density is less than water. The density of water is 1 g/cc whereas that of ice is 0.93 g/cc.
