Explanation / Answer

(a) B = k I / r = 2 x10-7 * 2.0 / 0.17 =     2.353 x10-6 Tesla . (b)   B = k I / r = 2 x10-7 * 3.8 / 0.17 =     4.471 x10-6 Tesla . (c) the forces are the same and are equal to .     force per unit length = currentof one wire * B field from the other = .                  =    3.8 * 2.353 x 10-6=    8.941 x10-6   newtons per meter . Or         2.0 * 4.471x 10-6   =    8.941 x10-6    newtons per meter . (c) the forces are the same and are equal to .     force per unit length = currentof one wire * B field from the other = .                  =    3.8 * 2.353 x 10-6=    8.941 x10-6   newtons per meter . Or         2.0 * 4.471x 10-6   =    8.941 x10-6    newtons per meter
