Question

1. what is the force of gravitational attraction between two 60 kg students who are standing 1.00 m apart? (a) 60×10^(-6) n (b) 120 n (c) 2.40×10^(-2) n (d) none of the above

Explanation:

Step1: Identify the gravitational - force formula

The formula for the gravitational force between two objects is $F = G\frac{m_1m_2}{r^2}$, where $G = 6.67\times10^{- 11}\ N\cdot m^2/kg^2$ is the gravitational constant, $m_1$ and $m_2$ are the masses of the two objects, and $r$ is the distance between them.

Step2: Substitute the given values

Here, $m_1=m_2 = 60\ kg$ and $r = 1.00\ m$. Substitute these values into the formula:
$F=6.67\times 10^{-11}\frac{60\times60}{1^2}$
$F=6.67\times10^{-11}\times3600$
$F = 2.4012\times10^{-7}\ N$

Answer:

D. none of the above
