Two electrons in an atom are separated by 1.6 × 10-10 m, the typical size of an atom. What is the force between them? Coulomb constant is 9 × 10⁹ Nm²/C². Answer in units of N. The T 06

The electric dipole in the figure consists of two charges, +Q and -Q, that are a distance, d, apart, where Q = 55.4 nC and d = 56.3 cm. Point A, which lies along the vertical (dotted) line midway between the two dipole charges, is an unknown distance, r, from the +Q charge. SYMBOLIC INPUT. Use the variables from the problem: Q, d, r, and Coulomb's constant, k, as needed. Electric Potential (1 of 2) The electric potential at point A will be ---Select--- The electric potential at point B will be ---Select--- This tells you that the electric field is ---Select--- the middle line. -.

An infinite line of positive charge lies along the y axis, with charge density A = 1.10 µC/m. A dipole is placed with its center along the x axis at x = 21.0 cm. The dipole consists of two charges ±10.0 µuC separated by 2.00 cm. The axis of the dipole makes an angle of 25.0° with the x axis, and the positive charge is farther from the line of charge than the negative charge. Find the net force exerted on the dipole.

The 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 ✈
