Water has a mass per mole of 18.0 g/mol, and each water molecule (H2O) has 10 electrons.
(a) How many electrons are there in 8.41 liters of water? (1 liter is equivalent to 1.00 × 10-3 m3)
(b) What is the net charge of all these electrons?
describes the net gravitational force on the particle due to the shell? zero if the particle is at the center of the shell but nonzero at other locations within the hollow zero for any location of the particle within the hollow.
