Can you please help me solve r1/r2 = sqrt(M2/M1)for M1.

My answer:
M1=M2r2^2/r1^2 Is this correct?

You are correct.

Thank you very much DrBob222

To solve the equation r1/r2 = √(M2/M1) for M1, you can follow these steps:

1. Start by squaring both sides of the equation to eliminate the square root: (r1/r2)^2 = M2/M1.

2. Multiply both sides of the equation by M1 to isolate it on one side: M1 * (r1/r2)^2 = M2.

3. Divide both sides of the equation by (r1/r2)^2: M1 = M2 / (r1/r2)^2.

4. Simplify further: M1 = M2 * (r2/r1)^2.

Therefore, your answer of M1 = M2 * (r2/r1)^2 is correct!
