Answer:

The answer is "[tex]\bold{ F2 = \frac{F F1}{(F1-F)}}[/tex]"

Step-by-step explanation:

Given:

[tex]\bold{F = \frac{F1 F2}{(F1 + F2)}}\\\\[/tex]

Cross multiplication:

[tex]\to F (F1 + F2) = F1 F2\\\\\to F F1 + F F2 = F1 F2\\\\\to F F1 = F1 F2 - F F2 \\\\\to F F1 = F2 (F1 - F) \\\\\to F2 = \frac{F F1}{(F1-F)}[/tex]
