two objects attract each other gravitationally with a force of 2.5^-10N.when they are 0.25m apart. Their total mass is 4.00kg. Find the individual mass?

F = GmM/r^2

2.5*10^-10 = 6.674*10^-11 * x(4-x) / .25^2
x = 0.059
4-x = 3.941

To find the individual mass of the two objects, we can use the formula for gravitational force:

F = G * (m1 * m2) / r^2

where:
F is the gravitational force
G is the gravitational constant (approximately 6.67430 × 10^-11 N(m/kg)^2)
m1 and m2 are the masses of the objects
r is the distance between the objects

Given:
F = 2.5 × 10^-10 N
r = 0.25 m
m1 + m2 = 4.00 kg

Let's substitute the given values into the formula and solve for the individual masses:

2.5 × 10^-10 = (6.67430 × 10^-11) * (m1 * m2) / (0.25)^2

Multiplying both sides by (0.25)^2:

2.5 × 10^-10 * (0.25)^2 = (6.67430 × 10^-11) * (m1 * m2)

6.25 × 10^-11 = (6.67430 × 10^-11) * (m1 * m2)

Now, substitute the value of m2 in terms of m1:

m1 + m2 = 4.00
m2 = 4.00 - m1

Substitute this value into the equation:

6.25 × 10^-11 = (6.67430 × 10^-11) * (m1 * (4.00 - m1))

Distribute the terms:

6.25 × 10^-11 = (6.67430 × 10^-11) * (4.00m1 - m1^2)

Rearrange the equation:

0 = (6.67430 × 10^-11) * m1^2 - (6.67430 × 10^-11) * 4.00m1 + 6.25 × 10^-11

This is a quadratic equation in terms of m1. Let's solve for m1 using the quadratic formula:

m1 = (-b ± √(b^2 - 4ac)) / (2a)

a = (6.67430 × 10^-11)
b = - (6.67430 × 10^-11) * 4.00
c = 6.25 × 10^-11

Substitute these values into the quadratic formula:

m1 = [-(6.67430 × 10^-11) * 4.00 ± √((6.67430 × 10^-11) * 4.00)^2 - 4 * (6.67430 × 10^-11) * (6.25 × 10^-11)] / (2 * (6.67430 × 10^-11))

Simplifying:

m1 = [-2.66972 × 10^-10 ± √(4.27843 × 10^-20 - 1.33486 × 10^-20)] / (1.33486 × 10^-10)

m1 = [-2.66972 × 10^-10 ± √(2.94357 × 10^-20)] / (1.33486 × 10^-10)

Let's calculate the two possible values for m1:

m1 = (-2.66972 × 10^-10 + √(2.94357 × 10^-20)) / (1.33486 × 10^-10)
m1 = 2.00001 kg

m1 = (-2.66972 × 10^-10 - √(2.94357 × 10^-20)) / (1.33486 × 10^-10)
m1 = 1.99999 kg

Therefore, the individual masses of the two objects are approximately 2.00001 kg and 1.99999 kg.

To find the individual mass of the objects, we can use Newton's law of universal gravitation, which states that the force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Let's break down the information given:
- Force of attraction between the objects: 2.5^-10 N
- Distance between the objects: 0.25 m
- Total mass of the objects (sum of individual masses): 4.00 kg

We can use the formula for gravitational force:

F = G * (m1 * m2) / r^2

Where:
F is the force of attraction
G is the gravitational constant (approximately 6.67430 × 10^-11 N m^2 / kg^2)
m1 and m2 are the individual masses of the objects
r is the distance between the objects

We can rearrange the formula to solve for the individual masses:

m1 * m2 = (F * r^2) / G

Given that the total mass (m1 + m2) is 4.00 kg, we can write:

m1 + m2 = 4.00 kg

Now, let's substitute the values into the equation:

(m1 + m2) = (2.5^-10 N * (0.25 m)^2) / (6.67430 × 10^-11 N m^2 / kg^2)

Simplifying this equation gives us:

4.00 kg = (2.5^-10 N * 0.0625 m^2) / (6.67430 × 10^-11 N m^2 / kg^2)

Next, we can isolate one of the masses in terms of the other:

m2 = 4.00 kg - m1

Now, we substitute the expression for m2 into the equation:

m1 + (4.00 kg - m1) = (2.5^-10 N * 0.0625 m^2) / (6.67430 × 10^-11 N m^2 / kg^2)

Simplifying further:

4.00 kg = (2.5^-10 N * 0.0625 m^2) / (6.67430 × 10^-11 N m^2 / kg^2)

Finally, solve for m1:

m1 = [(2.5^-10 N * 0.0625 m^2) / (6.67430 × 10^-11 N m^2 / kg^2)] - 4.00 kg

Using a calculator, you should be able to find the value of m1. Similarly, you can find m2 by subtracting m1 from 4.00 kg.
