For the radius it is supposed to be r^2. Would I use 10.0cm^2 or 5cm^2? and would I convert that value to meters? Also where did the 1.41s come from? Thank you

Four identical masses of 800kg each are placed at the corners of a square whose side length is 10.0cm. What is the net gravitational force (magnitude and direction) on one of the masses, due to the other three? I think I have to separate the four masses but I'm not sure ...

In a Cavendish balance apparatus suppose that M1= 1.10Kg, M2= 25.0Kg, and the rod connecting the M1 pairs is 30.0cm long. If, in each pair, M1 and M2 are 12.0cm apart center-to-center, find (a) the net force and (b) the net torque (about the rotation axis) on the rotating part...

The greater of two consecutive even integers is six less than twice the smaller. Find the integers. The greater of two consecutive even integers is six less than twice the smaller. Find the integers How about x + 2 = 2x - 6 almost .. it's x + (x+2)=2x-2

Math
The greater of two consecutive even integers is six less than twice the smaller. Find the integers. Let the smaller be x. That means that the larger is x+2. From your statement x+2=2x-6 Solve for x. I hope this helps. Thanks for asking.
