Homework Statement
Sphere 1 has net positive charge Sphere 2 has net negative charge Sphere 3 has net positive charge
The ranking of net charge magnitudes are
SPHERE 3 > SPHERE 2 > SPHERE 1
All spheres are conductors
Sphere 2 is moved away from Sphere 1 and toward Sphere 3 so that 2 and 3 touch.
Rank the charge density at each labeled point A  E, greatest first. (Note that point E indicates the left side of Sphere 3; there is no labeled point on the right side of Sphere 3.)
Rank positive charge greater than negative charge. Include zero in your ranking.
HINT: Image what would happen is Sphere 1 were removed; then, consider what effect Sphere 1 has on Spheres 2 and 3 when it is present.
Homework Equations
None
The Attempt at a Solution
Sphere 3 has net positive charge and has the highest magnitude of net charge, sphere 3 is pushing the positives in sphere 2 to point C and since sphere 3 has the most net charge points E and D now have net positive charge, sphere 1 is net positive so it is pushing the positives in sphere 2 towards sphere 3 so I think C, D & E are all positively charged now and all the negative charged has transferred to the right corner of sphere 3. since sphere 1 is net positive I feel A and B are also positively charged
