SUMMARY
The length of the wire inside a 5.3 T uniform magnetic field, experiencing a magnetic force of 6.5 N with a current of 5.0 A, is calculated using the formula F = B . I . L. The correct calculation yields L = 6.5 N / (5.3 T * 5.0 A), resulting in a length of 0.25 m. Despite the calculation being accurate, the homework system incorrectly marked it as wrong, indicating a potential issue with the system rather than the solution itself.
