Two point masses each equal to 1 kg attract one another with a force of 10–10N. The distance between the two point masses is..
Answers
m = mass of each point mass = 1 kg
F = gravitational force of attraction between the two masses = 10⁻¹⁰ N
r = distance between the two point masses = ?
G = universal gravitational constant = 6.67 x 10⁻¹¹
gravitational force of attraction between the two masses is given using newton's law gravitation as
F = G m²/r²
inserting the values in the equation
10⁻¹⁰ = (6.67 x 10⁻¹¹) (1)²/r²
r = 0.82 m

Answer:
0.8m
80 cm
Explanation:
m = mass of each of the two objects = 1 kg
F = gravitational force of attraction between the two objects = 10⁻¹⁰ N
r = distance between the two objects
G = universal gravitational constant = 6.67 x 10⁻¹¹ Nm²/kg²
Using newton's law of gravitation, force of attraction between the objects is given as
F = G m²/r²
multiplying both side by "r²"
Fr² = G m²
dividing both side by "F"
r² = G m²/F
taking square root both side
r = √(G m²/F)
inserting the above values
r = √((6.67 x 10⁻¹¹) (1)²/(10⁻¹⁰))
r = 0.82 m
