In a rectangular coordinate system a positive point charge q = 6.0×〖10〗^(-9) C is placed at the point (x. y) = (+0.15m,0) and an identical point charge is placed at (x. y) = (-0.15m,0). Find the x- and y-components, the magnitude, and the direction of the electric field at (x. y) = (+0.15m,-0.4m)

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge
