Three point charges are fixed in the x-y plane, as shown in the figure. The charges are QA = 2 × 10-6 C, QB = – 2 × 10-6 C, and QC = 2 × 10-6 C. The (x, y) coordinates of each charge are indicated in the figure, with coordinates given in meters (m). Find the x-component of the net electric force (magnitude only) on charge C (in N).

An unknown charge Q is located at the origin. Two points, A and B, are shown in the x-y plane. The electric potential at point A is 200 V. What is the electric potential at point B = (0 m, 3 m) (in V)? Assume the electric potential at infinity is zero. [Hint: you do not need to find Q value.]

Two point charges, A and B, are fixed in the x-y plane, as shown in the figure. The charges are QA = +3 × 10-7 C and QB = – 2 × 10-7 C. The (x, y) coordinates of each charge and a point P are indicated in the figure, with coordinates given in meters (m). What is the magnitude of the electric field at point P (in N/C)? 

A uniform electric field points vertically downward. A point object of mass 0.2 kg and charge −0.2 C is accelerating vertically upward with an acceleration of 20 m/s². What is the magnitude of the electric field (in N/C)?

A point charge A has a charge of +3 × 10-8 C. The (x, y) coordinates of the charge and a point labeled P are shown in the figure, with coordinates given in meters. What is the magnitude of the electric field due to charge A at point P (in N/C)?

A spherical conductor with a radius of 0.5 m carries a total charge of 5 × 10-6 C. A point charge of 2 × 10-6  C is placed at its center. What is the magnitude of the electric field at point A that is located at r = 0.4 m from the center of the sphere (in N/C)?
