Uma carga puntiforme de + 3,0uC é colocada em um ponto P de um campo elétrico gerado por uma partícula eletrizada com carga desconhecida Q. ficando sujeita a uma forca de atração de modulo 18 N. Sabendo que o meio e o vácuo (K = 9,0.10^9 Nm^2C^-2), determine: a) a intensidade do campo elétrico no ponto P; b) a carga fonte Q. O ponto P está a 30cm dessa carga.

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
