The formula for Newton's law of universal gravitation is:
F = (G * m1 * m2) / r^2
Where:
F is the gravitational force of attraction
G is the gravitational constant (approximately 6.67 x 10^-11 N(m/kg)^2)
m1 and m2 are the masses of the two objects
r is the distance between the centers of the two objects
In this case, the mass of the girl (m1) is 42.0 kg, the mass of the boy (m2) is 56.0 kg, and the distance between them (r) is 3.0 m.
Plugging in the values into the formula, we get:
F = (6.67 x 10^-11 N(m/kg)^2 * 42.0 kg * 56.0 kg) / (3.0 m)^2
Simplifying further:
F = (6.67 x 10^-11 N(m/kg)^2 * 2352 kg^2) / 9.0 m^2
F = (1.569 x 10^-7 N(m/kg)^2 * kg^2) / m^2
Finally, calculating the approximate value:
F ≈ 1.7 x 10^-6 N
Therefore, the approximate gravitational force of attraction between the girl and the boy is approximately 1.7 x 10^-6 Newtons.
