Electric field of circular ring
WebJun 3, 2024 · Flux is defined as a dot product of the area and the field, here it is an electric field: Φ = E ⋅ A, or Φ = E A cos θ, where θ is the angle between the electric field and the area normal. Since angle θ changes in time (because the ring rotates), the flux changes periodically as the cos θ does: decreases for θ ∈ ( 0 + π, π 2 + k π) WebAn annulus is a thin circular disk with a hole in it (or you can think of it as a ring with nonzero thickness). Here we will consider a charged annulus: charge is uniformly distributed between an inner radius R1 and an outer radius R2. a) Determine the electric field a distance z above the center of the annulus. Do this two ways: - First, do this
