Point charge q1 = -5.00 nC is at the origin and point charge q2 = +3.00nC is on the x -axis at x = 3.00cm. Point P is on the y-axis at y = 4.00cm. (A)Calculate the electric fields E 1 and E 2 at point P due to the charges q1 and q2.(Express your answer in newtons per coulomb in terms of the unit vectors i^, j^. Enter your answers separated by a comma.) (B) Use the results of part (a) to obtain the resultant field at P, expressed in unit vector form.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
