multiple choice 1 point
the equation for hookes law (formula to find the spring force) is
f = mg
f = -kx
f = ma
f = \frac{gm_1m_2}{r^2}

Explanation:

Hooke's Law states that the force exerted by a spring is proportional to the displacement from its equilibrium position. The negative sign indicates that the force is in the opposite direction of the displacement.

• \(F = mg\) is the formula for weight (force due to gravity).
• \(F = ma\) is Newton's second law.
• \(F=\frac{Gm_1m_2}{r^2}\) is the formula for gravitational force.

Answer:

B. \(F = -kx\)
