The drawings show three charges that have the same magnitude but may have different signs. In all cases the distance d between the charges is the same. The magnitude of the charges is |q| = 8.6 μC, and the distance between them is d = 3.8 mm. Determine the magnitude of the net force on charge 2 for each drawing.

Please provide what formula is used and why

In a vacuum, two particles have charges of 9₁ and 92, where q₁ = +5.0 μC. They are separated by a distance of 0.32 m, and particle 1 experiences an attractive force of 3.2 N. What is the value of q2, with its sign? Number i Units

Consider the diagram of the two charges shown below. The charge qA=-5.70 x 10-8 C while the distance x=0.260 m and the distance y=2.80 m. If the electric field due to the charges at point P is equal to zero, what is the charge qB? If the charge is negative include the negative sign. If the charge is positive do NOT include the sign of the charge Express your answer in Coulombs x 10-8 to two decimal places but do not include units in your answer. For example, if your answer was 2.31x 10-8 C you would input 2.31 in the box below.

Two small balls, each of mass 5.5 g, are attached to silk threads 40 cm long, which are in turn tied to the same point on the ceiling, as shown below. When the balls are given the same charge Q, the threads hang at 5.0° to the vertical, as shown below. What is the magnitude of Q? How do the signs of the two charges compare? Hint 5.0° Q The magnitude of Qis charge. Question Help: Message instructor Submit Question μC, and the two charges carry Select an answer sign of
