Acharge +q is located at the origin, while an identical charge islocated on the x axis at x= +0.50 m. a third charge of +2 q islocated on the x axis at such a place that the net electrostaticforce on the charge at the origin doubles, its direction remainingunchanged. where should the third charge be located.

This is the substance(s) formed in a chemical reaction.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
