In the figure below, the current in the long, straight wire is I1 = 19.8 A and the wire lies in the plane of the rectangle loop, which carries a current of I2 = 10 A . The dimensions in the figure are c = 0.1 m, a = 0.15 m, and , l = 0.45 m. Find the magnitude of the net force exerted on the loop by the magnetic field created by the wire.

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
