In the diagram, q1 = +0.250 mC, q2 = -0.180 mC, and q3 = +0.400 mC. the net force on q2 is zero. how far is q2 from q3?

(make sure you know the direction of each force!)

(hint: milli means 10^-3.)

(unit = m)

The gravitational force between pluto and charon is 3.61 × 1018 n. pluto has a mass of 1.3 × 1022 kg, which is only slightly greater than charon’s mass of 1.6 × 1021 kg. how far apart are pluto and charon? 2.0 × 107 m 2.4 × 1012 m 3.8 × 1014 m 5.8 × 1024 m
