Covers 21.5-21.7 Charged Rod 23:10, calculus, numeric, > 1 min, normal. 001 A rod 14 cm long is uniformly charged and has a total charge of- 22 μ C. The Coulomb constant is 8 . 98755 × 10 9 N · m 2 / C 2 . Determine the magnitude of the electric field along the axis of the rod at a point 36 cm from the center of the rod. Answer in units of N / C. Charged Semicircle 23:10, calculus, numeric, > 1 min, normal. 002 Consider the setup shown in the figure be- low, where the arc is a semicircle with radius r . The total charge Q is negative, and dis- tributed uniformly on the semicircle. The charge on a small segment with angle Δ θ is labeled Δ q . x y------------------ Δ θ θ r x y I II III IV B A O Δ q is given by 1. None of these 2. Δ q = Q 3. Δ q = Q Δ θ 2 π 4. Δ q = 2 Q Δ θ π 5.
