A line of positive continuous charge is formed into a semicircle of radius R = 68 cm depicted below. The total charge of this semicircle Q = 10 μC. This charge, however, is distributed not uniformly along the semicircle but with the angle-dependent linear charge density λ(θ) = λ0cos⁡θ. What is the value of parameter λ0? λ0 = μC/cm. Find now the electric field at the central point P in terms of its Ex and Ey components (with respect to the axes shown in the figure). Ex = N/C Ey = N/C

Q2-(25 pts) A variable resistor, R, whose value ranges from 0 to ∞ is connected between the terminals of a battery that has an emf ε = 18.0 V, and an internal resistance of 4.00 Ω. The ammeter and voltmeter are idealized meters. a) (8 pts.) As R varies over its full range of values, what will be the largest and smallest readings of the voltmeter and ammeter? Justify each answer with statement and/or direct calculation below. b) (8 pts.) The power dissipated at the variable resistor is 18.0 W. What can be the maximum reading on the voltmeter in this case? c) (9 pts.) Suppose we replace the variable resistor with a cylindrical wire of length 8.0 cm and cross section diameter 0.5 cm. The voltmeter reads 15.0 V. Calculate resistivity of the cylindrical wire, the magnitudes of the current density and the electric field through the wire. V18W = J = E = ρ =
