Question

What is the gravity force between two stars with mass of 5,000,000 kg and 1,000,000 kg if the distance between them is 100 m

If your answer is in scientific notation please convert it. Keep only the first 3 non zero digits. (example 1.2345 x 10^5 is 123000 and 1.2345 x 10^-3 is 0.00123)

Answer 1

0.0334N

Step-by-step explanation:

Given parameters:

M1 = 5 x 10⁶kg

M2 = 1 x 10⁶kg

Distance = 100m

Unknown:

Gravitational force = ?

Solution:

To solve this problem, we use the Newton's law of universal gravitation.

Fg =
`(G m1 m2)/(r^(2) )`

G is the universal gravitation constant

m is the mass

r is the distance

Fg =
`(6.67 x 10^(-11) x 5 x 10^(6) x 1 x 10^(6) )/(100^(2) )` = 0.0334N
