Forces on charged particles

Question 1

In a Cathode ray tube what do cathode and anode do?

Answer 1

Accelerate electrons - higher polarity = increased velocity

Question 2

In a Cathode ray tube what does y-plate do?

Answer 2

Control electron deflection - higher polarity = larger difference in height

Question 3

What must charged particles be doing to create a magnetic Field?

Answer 3

They must be moving

Question 4

In linear particle accelerators why do the length of the drift tubes increase?

Answer 4

So that the time taken through each tube is the same - since the particle velocity will have increased

Question 5

Right hand rule - positively and negatively charged particles

Answer 5

Right hand for electrons and negatively charged particles, left hand for protons and positively charged particles
