When the distance between two masses is doubled, the gravitational attraction between
1 answer:
The new gravitational attraction will be 1/4 as much
Explanation:
The magnitude of the gravitational force between two objects is given by
where
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
In this problem, the original force between the two objects is F, when they are separated by a distance r.
Later, the distance between the two objects is doubled, so the new distance is
Therefore, the new force will be
Therefore, the new force will be one-fourth as much.

Before getting an answer for it first we have to understand nuclear fusion.
Nuclear fusion is a thermo-nuclear reaction in which two light unstable nuclei will form a heavy stable nuclei. In this process there will be some mass defect which will be converted into energy as per Einstein's mass energy equivalence theorem.
The theorem is stated as where c is the velocity of light and m is the mass converted into energy.
One take an example of fusion in sun where 4 hydrogen atoms combine to form a helium nucleus which are explained below-
-----------------------------------------------------------------------
Here is the positron.
In this process very high temperature is needed which is approximately equal to the temperature of the sun i.e
Such temperature is very difficult to initiate the reaction on the earth surface. It should be carried out in an sustainable way also .Otherwise It will cause nuclear hazards.

<em>Hello, </em>
<h3><u>QUESTION)</u></h3>According to the second Newton's Law,
<em>✔ We have : F = m x a ⇔ m = F/a </em>
- m = 3000/15
- m = 200 kg
The mass of the object is therefore 200 kg.
