Two point charges are lying on the y- axis as in the figure: q1 = -4.10 µC and q2 = +4.10 µC. They are equidistant from the point P, which lies on the x- axis. (a) Find the electric field vector field at P? [Hint: Pay attention if any components cancel, saves your calculation] (b) A small object of charge q0 = 8.10 µC and mass m = 1.15 g is placed at P. When it is released, what is the magnitude of its acceleration?

Two point charges q1 and q2 are held in place 4.50 cm apart. Another point charge Q = -1.75 μC of mass m = 4.50 g is initially located 3.00 cm from each of these charges (the figure(Figure 1)) and released from rest. You observe that the initial acceleration of point charge Q is a = 344 m/s2 upward, parallel to the line connecting the two point charges. Find q1 and q2. Enter your answers numerically separated by a comma.

Two point charges q1 and q2 are held in place 4.50 cm apart. Another point charge Q = -2.35 μC of mass m = 5.00 g is initially located 3.00 cm from each of these charges (the figure(Figure 1)) and released from rest. You observe that the initial acceleration of point charge Q is a = 354 m/s2 upward, parallel to the line connecting the two point charges.

Fig: Two point charges q1 and q2 are fixed in place on an xy plane. Charge q1 = 1.777e-09 coulombs @ (1,4) meters. Charge q2 = 3.079e-09 coulombs @ (5,0) meters. Point P has no charge and is located at (5,4) meters. Calculate the magnitude of the electric field at point P in N/C.
