Electric Field Calculations for Stationary Charges and a Dipole at Point P(0,4m)

[QUOTE="TSny, post: 5344565, member: 229090"] WELCOME TO PF. OK. But I would keep an extra significant figure while doing the calculations. Then round off to the appropriate number of significant figures at the end. Also, don't forget the units. Electric field is a vector quantity. It is not good language to say that a vector is negative. However, the [I]components[/I] of a vector can be negative or positive. So, if the field points downward (along the negative y axis) then you would say that the y component of the electric field is negative. This does not look right. Are you trying to find the angle that E[SUB]2[/SUB] makes to the horizontal direction or the vertical direction? If you are constructing a right triangle to help find the angle, make sure you have the dimensions of the sides of the triangle correct. [/QUOTE]
