This is an approximate model of a water molecule. Point charges q1 and q2 of -1.00 x 10-19 C and 1.00 x 10-19 C, respectively, are placed 0.600 x 10-12 m apart. Thus d = 0.300 x 10-12 m in fig. 2 below, D= 0.600 x 10-12 m At point b, what must be the y-component Eynet of the net electric field due to the two charges? Show work.  At point b, what is the x-component Exnet of the net electric field due to the two charges? At point b, what is the direction of the net electric field due to the two charges? Indicate this direction by drawing an arrow in fig. 2 with its tail at point b. At point b, what is the magnitude of the net electric field due to the two charges? What is the relationship between your answer here and your answer to part (e)?
