- A uranium nucleus has 92 protons. Assume the nucleus to be a point-like object with charge Q = 92e, and ignore interaction with other electrons. a. Determine the magnitude of the E field at a distance of 6.0×10−13 m from the nucleus (about the radius of the innermost electron orbit around the nucleus). b. What is the magnitude of the force exerted on an electron by this E field?arrow_forwardIn Figure P24.49, a charged particle of mass m = 4.00 g and charge q = 0.250 C is suspended in static equilibrium at the end of an insulating thread that hangs from a very long, charged, thin rod. The thread is 12.0 cm long and makes an angle of 35.0 with the vertical. Determine the linear charge density of the rod.

Figure P23.61arrow_forwardThree charged spheres are at rest in a plane as shown in Figure P23.70. Spheres A and B are fixed, but sphere C is attached to the ceiling by a lightweight thread. The tension in the string is 0.240 N. Spheres A and B have charges qA = 28.0 nC and qB = 28.0 nC. What charge is carried by sphere C?arrow_forwardEight small conducting spheres with identical charge q = 2.00 C are placed at the corners of a cube of side d = 0.500 m (Fig. P23.75).

Figure P24.30 shows the magnitude of the electric field as a function of radial position r measured from the center of the sphere. Figure P24.30arrow_forwardA 8.15 nC charge is located 1.69 m from a 3.82 nC point charge. (a) Find the magnitude of the electrostatic force that one charge exerts on the other. N (b) Is the force attractive or repulsive? attractive repulsivearrow_forward? There are two identical, positively charged conducting spheres fixed in space. The spheres are 39.2 cm apart (center to center) and repel each other with an electrostatic force of F₁ = 0.0675 N. A thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed, the spheres still repel, but with a force of F2 = 0.100 N. The Coulomb force constant is k = 1/(4л€) = 8.99 × 10⁹ Nm²/C². Using this information, find the initial charge on each sphere, q1 and 92, if q1 is initially less than 92. 91 = 92 = 4.73 ×10-7 Incorrect 17.2 X10-7 Incorrect C Carrow_forward
