45 Consider two charges q1 = -27 e and q2 = -18 e at positions (31, 20, – 50) and (, , 37) V3 -9 m or nano meters. If position respectively where all the coordinates are measured in the scale of 10 vector of the charge q1 is 71 and charge q2 is T2. a) Find the relative position vector that points from charge q1 to charge q2. x component Give your answer to at least three significance digits. y component Give your answer to at least three significance digits. z component Give your answer to at least three significance digits.

Part A Calculate the magnitude of the electric field at the center of a square 42.5 cm on a side if one corner is occupied by a -38.8 µC charge and the other three are occupied by -26.5 µC charges. Express your answer to three significant figures and include the appropriate units. HA ? E = Value Units Submit Request Answer Part B Choose the correct direction of the electric field at the center of the square. toward to –38.8 µC charge perpendicular to the diagonal passing through –38.8 µC charge outward of –38.8 µC charge

Given the diagram where q1 is the positive and q2 is the negative charge, while q0 is (0,d), answer the following: a.) What is the net electric field at q0? b.) What would be the electric force acting on charge q0?

Charge Q1 = -12.0 nC is placed at (x,y) = (8, 0) millimeters and charge Q2 = 5.6 nC is placed at (2, 9) millimeters on the coordinate system shown. Charge Q0 = -2.83 nC is at the origin.  Determine the magnitude of force on Q0.  Express your answer in nN (nanoNewtons).
