T =mu²/k -5mg. find k

We need some additional information or values to solve for k. As the equation stands, we cannot isolate k without knowing either T, mu, m, or g.

To find the value of k, we need to rearrange the formula and isolate k.

The given formula is: T = μ²/k - 5mg.

Step 1: Add 5mg to both sides of the equation to isolate the term containing k.
T + 5mg = μ²/k

Step 2: Multiply both sides of the equation by k to isolate it in the denominator.
k(T + 5mg) = μ²

Step 3: Divide both sides of the equation by (T + 5mg) to solve for k.
k = μ² / (T + 5mg)

Therefore, the value of k is μ² / (T + 5mg).
