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

Answer:

0.0334N

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  = $\frac{G m1 m2}{r^{2} }$  

G is the universal gravitation constant

m is the mass

r is the distance

         Fg  = $\frac{6.67 x 10^{-11} x 5 x 10^{6} x 1 x 10^{6} }{100^{2} }$   = 0.0334N
