#1. We have a hollow metal spherical shell with charge -q and with radius rb #2. We have a soild metal sphere supported by an insulating stand with charge +q and radius rb #3. The solid metal sphere is located in the center of the hollow metal spherical shell (aka. #2 is in #1) The question...

Teclo and Justin both of you were right! Thanks. The net force would be to the left hence negative and its to 3 sig figs. So the answer was -.00151 compared to my original: +0.001508. Thanks

The sum is not correct, I tried it. The two forces are pulling in opposite directions, so I think subtracting is much more appropriate to get the "net force" on the mass at the origin.

Three identical masses of 650 kg each are placed on the x-axis. One mass is at -13.0 cm, one is at the origin, and one is at 42.0 cm. What is the magnitude of the net gravitational force on the mass at the origin, due to the other two masses? I solved this problem in the homeowrk section of...
