The student is missing the gravitational constant, G. To calculate the gravitational force between two masses, you would use Newton's law of universal gravitation, which requires the values of the masses involved and the gravitational constant. The formula is:
\[ F = G \frac{m_1 m_2}{r^2} \]
where \( F \) is the gravitational force, \( G \) is the gravitational constant, \( m_1 \) and \( m_2 \) are the masses of the two objects, and \( r \) is the distance between their centers.
The student is missing the gravitational constant, G. To calculate the gravitational force between the Earth and the Sun, she needs this constant as part of the equation for gravitational force, which is given by:
\[ F = G \frac{m_1 m_2}{r^2} \]
where \( m_1 \) and \( m_2 \) are the masses of the Earth and the Sun, and \( r \) is the distance between them. The gravitational constant \( G \) is essential for determining the force.
