Final answer:
The gravitational force of attraction between two objects is 6.674 x 10^-11 N.
Step-by-step explanation:
The gravitational force of attraction between two objects can be calculated using Newton's law of gravitation, which states that the force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The equation for this force is:
F = G * (m1 * m2) / r^2
Where F is the gravitational force, G is the gravitational constant (6.674 x 10^-11 N.m^2/kg^2), m1 and m2 are the masses of the objects, and r is the distance between them.
Substituting the given values:
m1 = 2 x 10^20 kg, m2 = 10 kg, and r = 10^15 meters
F = (6.674 x 10^-11 N.m^2/kg^2) * ((2 x 10^20 kg) * (10 kg)) / (10^15 meters)^2
Simplifying the equation:
F = 6.674 x 10^-11 N
