Question

The figure below shows two wires, each carrying a current. The first wire consists of o circular arc of radius R = 2.8m and two equal radial lengths of L=0.75R; it

carries current I₁ = 27A. The second wire is long and straight; it carriers current I2 = 25A, and it is at distance d=0.5R from the center of the arc. At the instant shown a snapshot of a charged particle q moving at velocity v (7.8i +8.9j)m/s toward the straight wire. Find the magnitude of the magnetic force on the charged particle due to the wires in terms of quo. Express your final result using one decimal place. = 4. Z y Answer: >X L L R 45⁰ d 12
