The Gravitational Force Between Two Masses Is Modeled Using the Following

question 17

Multiple Choice

The gravitational force between two masses is modeled using the following function: $$F _ { g } ( r ) = G \frac { m _ { 1 } m _ { 2 } } { r ^ { 2 } }$$
where $F _ { g } =$ gravitational force (newtons)
$$\begin{array} { l } G = 6.673 ^ { \times } 10 ^ { - 11 } \frac { \mathrm { N.m } ^ { 2 } } { \mathrm {~kg} ^ { 2 } } \\m _ { 1 } = \text { mass number } 1 \text { (kilograms) } \\m _ { 2 } = \text { mass number } 2 \text { (kilograms) } \\r = \text { distance between centers of masses (meters) }\end{array}$$ Which type of mathematical model is used here to describe the gravitational force?

• A)Linear model
• B)Nonlinear model
• C)Exponential model
• D)Trigonometric model
