A negative charge is placed between a pair of oppositely charged plates, as shown. Two horizontal parallel plates have a negatively charged sphere labeled X right in between them. The top plate is positive and the bottom plate is negative.

Which best describes the result of moving the charge to the point marked X?

A. Its electric potential energy increases because it has the same electric field.
B. Its electric potential energy increases because the electric field increases.
C. Its electric potential energy stays the same because the electric field increases.
D. Its electric potential energy stays the same because it has the same electric potential.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
