Three positively charged particles, with charges q$1=$qq$1=$q$,$ q$2=2$qq$2=2$q$,$ and q$3=$qq$3=$q $($where q$>0$q$>0),$ are located at the corners of a square with sides of length dd$.$ The charge q$2$q$2$ is located diagonally from the remaining $($empty$)$ corner.

Find the magnitude of the resultant electric field E$$netE$$net in the empty corner of the square. Determine the magnitude EnetEnet of the net electric field at point P$.$ Use KK for the electrostatic constant.
