Question
A positive charge q1 = 2.70 μC on a frictionless horizontal surface is attached to a spring of force constant k as in Figure P15.12. When a charge of q2 = -8.60 μC is placed 9.50 cm away from the positive charge, the spring stretches by 5.00 mm, reducing the distance between charges to d = 9.00 cm. Find the value of k.

- I need help with this question. Thank you!arrow_forwardTwo identical, charged styrofoam balls are hung by threads from a ceiling, as shown in Figure 2. The balls each have a mass m = 425 g and the thread has a length of 30.0 cm. In equilibrium the angle 0 = 26.0°. What is the magnitude of the charge on each ball? (0) A q1 9₁ Enter your answer in µC.arrow_forwardTwo identical metal blocks resting on a smooth horizontal surface are connected by a lightweight spring having a spring constant k = 0.2 N/m, as shown in the figure. The length of the spring before it is stretched is L0 = 10 cm. A total charge Q is carefully applied to the block, which is assumed to be a point charge. Because the blocks are given an electric charge, the spring is stretched so that its length becomes L = 10.2 cm. Find Q!arrow_forward
- A 8-g charged plastic sphere charged to 75 µC is on top of a plastic spring with spring constant k = 400 N/m, which has a relaxed length of 10 cm. You then place another charged object 1 cm above (not touching) the sphere. Now, the spring is 9.5 cm long. Find the charge on the new second object.arrow_forwardThe figure below shows two identical small, charged spheres. One of mass 4.3 g is hanging by an insulating thread of length 20.0 cm. The other is held in place and has charge q₁ = -3 -3.1 μC. The thread makes an angle of 18° with the vertical, resulting in the spheres being aligned horizontally, a distance r apart. Determine the charge 92 on the hanging sphere. nC 20.0 cm 18⁰ 91 92 ✈arrow_forwardA 0.01294 kg ball with a positive charge of 47.4 μC hangs from a light string right next to a large vertical metal plate (the metal plate is so large compared to the length of the string and ball consider it to be infinite in size). How much surface charge density must the plate have to repel the ball so that the string makes and angle of 5.03 degrees from the vertical. Give your answer to 3 significant figures and in units of nC/m/m (nanoCoulombs per meter squared: Blackboard has trouble with squred units).
