Suppose you have 5 point charges q1 to q5 distributed along a semi-circle maintaining equal distance. The charge q6 is at the center of the circle. The radius of the semi-circle is R=20cm and the magnitude of the charges are as follows

Three charges are located as shown in the figure, with values q1 = 4.6 × 10-16 C, q2 = -1.9 × 10-16 C, q3 = 6.75 × 10-16 C. The charges are separated by d1 = 3.4 × 10-6 m and d2 = 4.5 × 10-6 m. a. What is the force of q2 on q1 in the x direction, Fx? Give your answer in newtons, and recall k = 8.988 × 109 N m2/C2.  b. What is the force of q3 on q1 in the y direction, Fy? Give your answer in newtons.

Four identical metallic spheres with charges of +9.0 µC, +2.6 µC, -3.4 µC, and -7.2 µC are placed on a piece of paper. The paper is lifted on all corners so that the spheres come into contact with each other simultaneously. The paper is then flattened so that the metallic spheres become separated. (a) What is the resulting charge on each sphere? µC (b) How many excess or absent electrons (depending on the sign of your answer to part (a)) correspond to the resulting charge on each sphere? electrons are ---Select--- Additional Materials Reading

Three point charges are shown below. q1 = 4.57 μC, q2 = 2.30 μC, and q3 = -15.5 μC. d1 = 6.00 cm and d2 = 4.00 cm. What is the magnitude of the net electric force on q3 in Newtons? 1.00 μC = 1.00 × 10-6 C, 1.00 cm = 1.00 × 10-2 m. Use K = 9.00 × 109 N·m2/C2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A small plastic ball of mass 8.19 × 10³ kg and charge +0.116 μC is suspended from an insulating thread and hangs between the plates of a capacitor (see the drawing). The ball is in equilibrium, with the thread making an angle of 30.0° with respect to the vertical. The area of each plate is 0.01280 m². What is the magnitude of the charge on each plate? 30.0⁰ IN + ++ + ▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Could I get help seeing how to solve this problem?

can you please answer (a) & (b)?

Two point charges are placed on the x axis as shown in (Figure 1). The first charge, q1q1q_1 = 8.00 nCnC , is placed a distance 16.0 mm from the origin along the positive x axis; the second charge, q2q2q_2 = 6.00 nCnC , is placed a distance 9.00 mm from the origin along the negative x axis.   Figure 1 of 2Two charges, labeled q 1 and q 2, are shown on the xy-plane. Point O is at the origin. Charge q 1, which is equal to 8 nanocoulombs, lies on the positive x-axis at distance 16 meters from the origin. Charge q 2, which is equal to 6 nanocoulombs, lies on the negative x-axis at distance 9 meters from the origin.   1.Find the x-component of the electric field at the origin, point O. Express your answer in newtons per coulomb to three significant figures, keeping in mind that an x component that points to the right is positive.   2. Now, assume that charge q2q2 is negative; q2=−6nCq2=−6nC, as shown in (Figure 2). What is the x-component of the net electric field at the origin,…
