>>>> Some questions in physics <<<<?

Question:1> What do you mean by "anode is at a higher potential to cathode" ?

2> What is the derivation of Force = Charge of electron * Intensity

3> How are cathode rays produced ??

4> Define electric field and magnetic induction .

5> Why does a electron travel in a CIRCULAR and not a PARABOLIC path when it passes through magnetic field perpendicular to direction of its velocity ? [ With reference to Thompsons cathode ray experiment ]

6> What do you mean when you say cathode is given increasing -ve potentials ??

Please try to answer all if possible and if not please answer atleast one,, i really need to know the answers to all the questions.

Hope you WILL help me ...

Thank you VERY VERY much in advance :O)

1) This basically means that the electrons are flowing from the anode to the cathode.

2) Ok, so the equation is F=Eq; the derivation is at the link below...

3) To see how they were originally developed look here...
Short answer: Cathode rays are emitted from the cathode in a discharge tube, when pressure is reduced to 0.01 mm of mercury.

4) electric field is the space surrounding an electric charge.
magnetic induction - the production of voltage across a conductor situated in a changing magnetic field

5) best i could find about Thompson

6) Sorry, i'm not sure what -ve potentials are?
