Question

Given two particles having a mass of 8,000 g and 12 kg, respectively separated by a distance of 2.5 ft. Determine the force of gravity acting between the two particles. Include all units within the equation showing which units cancel and which units remain. Express your final answer in Newton’s.

Answer 1

The value is
`F = 1.10 *10^(-8) \ N`

Step-by-step explanation:

Generally the gravitational force between the two particles is mathematically represented as

`F = (G * m_1 * m_2 )/(r^2)`

Here G is the gravitational constant with value
`6.67300 * 10^(-11) m^3. kg^(-1) s^(-2)`

substituting
`8,000 g =  8kg` for
`m_1` , 12 kg for
`m_2` and
`2.5 ft =   0.762 \  m` for r

`F =  (6.67300 * 10^(-11)   *  8  *  12 )/(0.762 ^2)`

`F = 1.10 *10^(-8) \  N`
