Question

A neutron star and a black hole are 3.34 x 1012 m from each other at a certain point in their orbit. The neutron star has a mass of 2.78×1030 kg and the black hole has a mass of 9.94×1030 kg. What is the magnitude of the gravitational attraction between the two?

Answer 1

F=1.65 x 10²⁶ N

Step-by-step explanation:

Given that

Distance ,R= 3.34 x 10¹² m

Mass m₁= 2.78 x 10³⁰ kg

Mass ,m₂= 9.94 x 10³⁰ kg

we know that gravitational force F given as

`F=G(m_1m_2)/(R^2)`

G=Constant

G=6.67 x 10⁻¹¹ Nm²/kg²

Now by putting the values

`F=6.67* 10^(-11)* (2.78* 10^(30)* 9.94* 10^(30))/((3.34* 10^(12))^2)\ N`

F=1.65 x 10²⁶ N

Therefore the force between these two mass will be 1.65 x 10²⁶ N.
