# Centripetal and centrifugal forces

**1. The problem statement, all variables and given/known data**

A space station is connected to a box(50kg) with a super strong string(1m) and it is rotating which makes the box rotate at a speed of 10m/s.

I am inside the box.

Find the force the box exerts on me.

**2. Relevant equations**

##F=m\frac{v^2}{r}##

**3. The attempt at a solution**

I found that centripetal force=5000N.

This force is exerted on the box by the string.

According to my experience,the "me" in the box would try to move opposite to the centripetal force direction but I heard that centrifugal force is not a real force.

So is the force exerted on me 5000N or something else?Can you explain why newton’s third law does not apply here?
