In addition to acceleration of gravity we experience centrifugal acceleration away from the axis of rotation of the earth. this additional acceleration has value ac = r w^2 where w = angular velocity and r is distance from your spot on earth to the earth's axis of rotation so r = R cos(l) where l = 60 deg is the lattitude and R the earth's radius and w = 1 / (24hr x 3600sec/hr)
<span>now you look up R and calculate ac then you combine the centrifugal acc. vector ac with the gravitational acceleration vector ag = G Me/R^2 to get effective ag' = ag -</span>
Explanation:
They will repel, meaning that they are made of an electrical conductor.

Where for the resistivity the one of the copper should be used: 
.
The area A is that of a circle, which written in terms of its diameter is:
Putting all together:
Which for our values is:
Explanation:
Newton's second law:
∑F = ma
277 N − 245 N = (25 kg) a
a = 1.28 m/s²
Saturn is a planet in solar system. It's ring is made out of small covered ice particle. It has over 30 moons.
