if the mass of two balls is 0.300 kg each then what is the gravitational force between them if the distance is 0.3000 m

same as problem above

This is the same as your problem above with the different planets and the weight of the man on each.

i didn't gets how to solve this one can u help me

Hey look. I showed you how to do it for the earth mass and man mass. Do the same for the two balls .3 m apart.

G * .3 *.3 / 3^2 = G

To calculate the gravitational force between two objects, you can use the equation for gravitational force:

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

Where:
F is the gravitational force between the two objects,
G is the gravitational constant (approximately 6.67430 x 10^-11 N m^2/kg^2),
m1 and m2 are the masses of the objects, and
r is the distance between the centers of mass of the objects.

In this case, the mass of each ball (m1 and m2) is given as 0.300 kg, and the distance (r) is given as 0.3000 m.

Plugging these values into the equation, we have:

F = (6.67430 x 10^-11 N m^2/kg^2) * (0.300 kg) * (0.300 kg) / (0.3000 m)^2

Now let's calculate it step-by-step:

Step 1: Calculate the square of the distance.
r^2 = (0.3000 m)^2 = 0.090 m^2

Step 2: Multiply the masses of the objects.
m1 * m2 = (0.300 kg) * (0.300 kg) = 0.09 kg^2

Step 3: Plug in the values into the gravitational force equation.
F = (6.67430 x 10^-11 N m^2/kg^2) * 0.09 kg^2 / 0.090 m^2

Step 4: Simplify the expression.
F = 6.67430 x 10^-11 N = 6.67 x 10^-11 N (in scientific notation)

Therefore, the gravitational force between the two balls is approximately 6.67 x 10^-11 Newtons.
