Homework Statement Basically, I am writing up a practical experiment dealing with Electrons in a uniform electric field (I.e. Using an electron gun). There are two parallel plates, one with a positive charge and one with a negative charge. Between these to plates is a grid which allows...

That's what gets me stumped though =/. The teacher says he is going to put in the test "Show that the radius is proportional to the Radius". What does it mean to be proportional. (It means they have a relationship I guess) But what would you write down for an answer asking if something is...

How is the Period proportional to the Radius. (The Period being how long it takes for 1 full revolution of an object) I am also assuming there is a tension force.

Don't know why it didnt work... should work now. Thankyou.

Hi, I missed two weeks of physics at school due to illness and I am having a hard time understanding a lot of the things our teacher set us to do. So I have these questions... 1. If an object is spinning in centripetal motion (View the dodgy diagram I made) View Image 'Diagram.png' If I...

You must be doing gravitational fields =p... I am up to that as well in my course. When they are referring to the planetary mass (Often reffered to as M) they are talking about the mass which is exerting the main centripetal force. (i.e. the mass which is being revolved around.) If more...

Thankyou for the help... I am starting to get it now. I will keep you informed of how well I did with the practical.

I can understand how the centripetal force can relate to the period. (Without the radius and velocity there would be no centripetal force acting) The thing I am finding hard to comprehend is why we need 1/T^2? Why make a graph of 1/T^2 against Force when it is just as simple to create T...

The point of the experiment is to find the relationship between 1/T^2 (T being the time it takes the object to complete one revolution) and the centripetal force. I have yet to find the relationship of them though... I am having a bit of trouble comprehending it.

I am currently doing a practical concerning centripetal motion and I am a bit confused. The attachment has the setup of the experiment. Now the aim of the experiment is to create a horizontal centripetal motion with plug. If we were to add more mass to the plastic bag would it increase...
