which equation is used to calculate the weight of an object on a planet?\n$w = mg$\n$w = mg$\n$w=\frac{m}{g}$…

Explanation:

Step1: Recall weight - mass relationship

Weight is the force exerted on an object due to gravity. The formula for weight ($w$) of an object with mass ($m$) in a gravitational - field with gravitational acceleration ($g$) is given by $w = mg$. Here, $G$ is the gravitational constant which is used in the law of universal gravitation $F=G\frac{m_1m_2}{r^2}$, not in the simple weight - mass formula for an object on a planet's surface.

Answer:

$w = mg$
