Coulomb's law estimates the force between two charges. Suppose the force between two given charges is F when separation distance between them is d. What is the new force between the same charges when separation distance between them is d/2 ? F/2 2F F/4 4F F

Two charges +2 µC and +8 µC are placed along the z axis, with the first charge at the origin (z =0) and the second charge at z = +1 m. Find the magnitude and direction of the net force on a -2 nC charge when placed at the following locations below. Overall Hint Review Section 5.3 Coulomb's Law. Use Coulomb's Law to calculate force due to each of two charges and add them together for the net force, minding the directions. For part (c), you will need to do the vector sum (more below). a. halfway between the two charges: magnitude of force is direction is Select an answer b. on the axis at x = -0.5 m: magnitude of force is is Select an answer c. at the coordinate (x, y) = (1 m, 0.5 m) (half a meter above the +8 µC charge in a direction perpendicular to the line joining the two fixed charges): Hint for (c) This problem is fully 2-dimensional. The charge at x = 1 m exerts force along y direction; the charge at the origin exerts force along the line connecting (x, y) = (0,0) and (z,y) = (1…

Two charges +4 µC and +11 µC are placed along the x axis, with the first charge at the origin (x = 0) and the second charge at x = +1 m. Find the magnitude and direction of the net force on a -9 nC charge when placed at the following locations below. Overall Hint Review Section 5.3 Coulomb's Law. Use Coulomb's Law to calculate force due to each of two charges and add them together for the net force, minding the directions. For part (c), you will need to do the vector sum (more below). a. halfway between the two charges: magnitude of force is direction is Select an answer b. on the x axis at x = -0.5 m: magnitude of force is direction is Select an answer c. at the coordinate (x, y) = (1 m, 0.5 m) (half a meter above the +11 µC charge in a direction perpendicular to the line joining the two fixed charges): Hint for (c) Magnitude of force is degrees below -x axis. mN, and the direction is mN, and the mN, and the

been stuck on this question for a while, would appreciate help If a particulate, with a mass of 2.1 x 10-5 kg, acquires a charge of 3.2  μC , the electrical force on the particulate, due to the electric field is:   a 4.3 x 10-2 N b 4.3 N c 4.3 x 106 N d 4.2 x 1011 N explanation would be highly appreciated!
