Question

3 -4 points Tipler6 27-P034. My Notes Three long, parallel, straight wires pass through the vertices of an equilateral triangle that has sides L5.40 cm, as shown in the figure below. A a dot indicates that the direction of the current is out of the screen and a cross indicates that the direction of the current is into the screen. Each current is 16.0 A. (a) Find the magnetic field at the location of the upper wire due to the currents in the two lower wires. magnitude directionSelect (b) Find the force per unit length on the upper wire. magnitude direction Select N/m eBook 4 173 points | Previous Answers Tipler6 27.P049.scln.

Explanation / Answer

a) B = 2 mu0 (2 I ) cos 30 / 4 pi R

= (2 * 10-7 * 2 * 16 * cos 30) / (5.4 * 10-2)

= 1.026 * 10-4 T = 102.6 muT

toward the right

b)F / l = 4 mu0 I2 cos 30 / 4 pi R

= (4 * 10-7 * 162 * cos 30 ) / (5.4 * 10-2)

= 1.64 * 10-3 N/m
