Rearranging the weight formula for mass

Steps:

• Recall the formula: weight = mass × gravitational field strength.
• Rearrange to solve for mass: mass = weight ÷ gravitational field strength.
• Identify X as the result (mass), Y as the numerator (weight), and Z as the denominator (gravitational field strength).
• Match to option A, which fits the rearranged equation.

Why A is correct:

• The formula mass = weight / gravitational field strength directly defines X as mass, Y as weight, and Z as gravitational field strength.

Why the others are wrong:

• B: Reverses mass and weight; weight equals mass × g, not mass / g.
• C: Mass is not gravitational field strength / weight; this inverts the relationship.
• D: Weight is not gravitational field strength / mass; it multiplies, not divides.

Final answer: A
