Question

Clark’s mass is 65 kg and Lana’s mass is 45 kg. If they are seated 2.0 m apart in their physics class, what is the force of gravitational attraction between Clark and Lana?

Answer 1

Force of gravity,
`F=4.87* 10^(-8)\ N`

Step-by-step explanation:

Mass of Clark,
`m_1=65\ kg`

Mass of Lana,
`m_2=45\ kg`

Distance between Clark and Lana, d = 2 m

We need to find the force of gravitational attraction between Clark and Lana. It is given by the formula as follows :

`F=G(m_1m_2)/(d^2)`

G is universal gravitational constant

`F=6.67* 10^(-11)* (65* 45)/((2)^2)`

`F=4.87* 10^(-8)\ N`

So, the force of gravity attraction between Clark and Lana is
`4.87* 10^(-8)\ N`. Hence, this is the required solution.
