Rice has a bulk of 0.9 g/mL, but an individual grain of rice has a density of 1.1g/mL. Water has a density of 1.0g/mL. what would happen to a cup of rice when poured into a lot of water?

Since the grains are not connected together, it's every grain for himself when they're dropped into the water.

The density of each grain is greater than the density of water, so each grain on its own sinks to the bottom.

The reason why a CUP or a BAG of rice has less density is because the grains don't all fit together perfectly, and 15% or 20% of the volume in the cup or bag is air, not rice grains.

answer; i believe that the correct answer is (d) a very small amount of mass

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
