Answer options with 4 options
A.
6.7 time 10 Superscript negative 11 Baseline newtons
B.
6.7 time 10 Superscript negative 11 Baseline kilograms
C.
6.7 times 10 Superscript negative 11 Baseline kilograms per meter
D.
6.7 time 10 Superscript negative 11 Baseline kilograms squared per meter squared
The formula to calculate gravitational force of attraction is:
F = (G * m1 * m2) / r^2
where F is the gravitational force, G is the universal gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.
In this case, we have two spheres of mass 2.0 kilograms each, and they are separated by 2.0 meters from center to center.
Plugging the values into the formula:
F = (6.7 * 10^-11 * 2.0 * 2.0) / (2.0^2)
= (6.7 * 10^-11 * 4.0) / 4.0
= 6.7 * 10^-11 newtons
Therefore, the gravitational force of attraction that exists between the two spheres is 6.7 * 10^-11 newtons.
So, the correct answer is:
A. 6.7 * 10^-11 newtons
