Problem 2 Two 10-cm-long rods are uniformly charged with ±10 nC and placed side by side, 4.0 cm apart. The rod on the left is positively charged and the rod on the right is negatively charged. What is the electric field at distances: 1.0, 2.0, 3.0 and 6.0 cm from the left rod along the line connecting the midpoints of the rods? +10 nC -10 nC 10 cm +++++++++++++++++++ 4.0 cm
Problem 4 A thin rod of length I has a total charge of Q spread uniformly across it. Find an expression for the electric field produced by this rod a distance r from it's center. (see figure). What does this expression reduce to for r > L? r +++++++++ Ans: E = 4kQ LDN/C L ++
Problem 5 The figures shows a cross-section of two very long wires, coming out of the page. The wire on the right carries a negative charge and the wire on the left carries a positive charge. The distance between the two wires is d = 10 cm. The charge densities are λ = ±1.0 × 10-7 C/m. Find the electric field at the dot, which is y = 15 cm above the adjoining line. Give you answer in component form. Y + d Very long wires, coming out of the page!
