Question 1 Report

The gravitational force between two objects  masses 1024 24 kg and 1027 27 kg is 6.67N. Calculate the distance between them [ G = 6.6 x 10−11 − 11 Nm2 2 kg−2 − 2  ]
Answer Details

To calculate the distance between two objects based on the gravitational force acting between them, we need to use the formula for gravitational force:


F = (G * m1 * m2) / r²


Where:

  • F is the gravitational force between the two masses (6.67 N).
  • G is the gravitational constant (6.6 x 10-11 Nm²/kg²).
  • m1 is the first mass (1024 kg).
  • m2 is the second mass (1027 kg).
  • r is the distance between the centers of the two masses.

We need to compute r by rearranging the formula:


r² = (G * m1 * m2) / F


Therefore, the distance r is:


r = √((G * m1 * m2) / F)


Substitute the given values into the equation:


r = √((6.6 x 10-11 Nm²/kg² * 1024 kg * 1027 kg) / 6.67 N)


Calculating inside the square root:

G * m1 * m2 = 6.6 x 10-11 * 1024 * 1027 = 6.6 x 1040 Nm²


Then divide by the force:

6.6 x 1040 Nm² / 6.67 N = 0.99 x 1040 m²


Finally, calculate the square root:

r = √(0.99 x 1040)

r ≈ 1.0 x 1020 m


Therefore, the distance between the two objects is approximately 1.0 x 1020 m.
