Force = mass * acceleration, with units kg*m / second squared, or the more commonly the Newton, N. Assuming objects freely fall due to gravity at 9.8 m/second squared, and zero air resistance force opposing the freely falling object, 1 kg * 9.8 m/second squared = 9.8 N = force on the ball.
Answer:
The force of gravitational attraction is 8.454 x 10⁻⁸ N.
Explanation:
Given;
mass of the boy, m₁ = 78 kg
mass of the girl, m₂ = 65 kg
distance between the boy and the girl, r = 2 meters
The force of gravitational attraction is given as;
where;
G is gravitational constant = 6.67 x 10⁻¹¹ Nm²/kg²
r is the distance between two masses, m₁ and m₂
Therefore, the force of gravitational attraction is 8.454 x 10⁻⁸ N.
