Which of the following is the correct formula for the weight (W) of an object of mass m? (g is the acceleration due to gravity.)
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → W = m × g
The weight of an object is the force with which the Earth pulls it. By Newton’s second law, force = mass × acceleration, and the acceleration here is g, so W = m × g, measured in newtons.
