Two charged particles are attached to an x axis: Particle 1 of charge – 2 × 10^-7 is at position x = 6.0 cm and particle 2 of charge + 2 × 10^-7 is at position x = 21.0

cm. Calculate the net electric field midway between the particles

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
