Two long, charged, thin-walled, concentric cylindrical shells have radii of 4.3 and 7.0 cm. the charge per unit length is 4.8 × 10^-6 c/m on the inner shell and -6.4 × 10^-6 c/m on the outer shell. what are the (a) magnitude e and (b) direction (radially inward or outward) of the electric field at radial distance r = 6.1 cm? what are (c) e and (d) the direction at r = 12 cm?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
