WebSep 9, 2015 · A thin flat washer lies in the x − y plane, with the center at the coordinate origin. The washer has an inner radius R1 and an outer radius R2 (so it looks like a disk of radius R2 with a concentric circular cut-out of radius R1). The surface of the washer is uniformly charged with a surface charge density σ. 1. WebConsider first the angular speed ( ω) is the rate at which the angle of rotation changes. In equation form, the angular speed is. ω = Δ θ Δ t, 6.2. which means that an angular rotation ( Δ θ) occurs in a time, Δ t . If an object rotates through a greater angle of rotation in a given time, it has a greater angular speed. Webthat the electric field is constant in magnitude on a sphere of radius centered on the chargeQ. The second point is that the electric field points radially away from . r Q Let’s calculate the flux of the electric field on a sphere of radius centered on . First we choose a small patch of that sphere of radius r Q ∆Ai. makwarela tvet college online application
