Two charges are placed as shown in the figure (a right triangle with the right angle at point P). The distance between charges is 13.0 cm. Point P is 5.0 cm from the charge q1 and 12.0 cm from the charge q2. The magnitude of is 3.00uC , but its sign and the value of the charge q2 are not known. The direction of the net electric field at point P is entirely in the negative y-direction.
Determine the magnitude of the electric field.

To answer this question the figure is needed. It is not clear how "y-direction" is related to the positions of the charges.

electric powered field E= - dV /dr As ability is persevering with dV / dr =0 consequently electric powered field is 0 in a region the place electric powered ability is persevering with. as an occasion, interior a hollow charged matallic sphere, the electrical powered field IS 0 however the means interior is persevering with and equivalent to ability on the suface of charged sphere
