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)? 

Three equal-magnitude point charges of varying signs are placed at three of the corners of a square of side d as shown in the figure. Which one of the arrows shown represents the direction of the net electric field at the vacant corner of the square?
