Final answer:
The ratio of the two fixed charges can be found by taking the square root of f l1/l2 and substituting the given value.
Step-by-step explanation:
The ratio of the two fixed charges can be found using the formula:
qa/qb = sqrt(f l1/l2)
Substituting the given value of f l1/l2 = 1.58, we can solve for the ratio:
qa/qb = sqrt(1.58)
qa/qb = 1.26
Therefore, the ratio of the two fixed charges is 1.26.
