Question

The resultant force, R, is related to two concurrent forces, X and Y, acting at right angles to one another, by the formula . Rewrite the formula for Y.

Answer 1

Y = √(R² - X²)

Explanation:

C

Answer 2

Y = √(R² - X²)

Explanation:

∵ The two forces acting at right angles to each other

∴ The resultant force R = √(X² + Y²)

∴ R² = X² + Y²

∴ Y² = R² - X²

∴ Y = √(R² - X²)
