A+4.00 μc point charge and -6.00 μc point charge are placed along the x-axis at x = 0.000 cm and x = 40.0 cm, respectively. where must a third charge, q, be placed along the x-axis so that it does not experience any net electric force due to the other two charges?

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
