forces on charged particles

Question 1

What happens to a charged particle in an electric field?

Answer 1

they experience a force

Question 2

Where do electric fields exist?

Answer 2

around charged particles and between charged plates

Question 3

What must fields lines do in charged parallel plates?

Answer 3

• point from positive to negative
• be parallel and at a right angle to the plates
• be equally spaced
• touch the plates

Question 4

What is the equation for work done?

Answer 4

W=QV

Question 5

What is the equation for kinetic energy?

Answer 5

Ek=1/2mv2

Question 6

What does a moving charge produce?

Answer 6

a magnetic field

Question 7

What can you use to determine the direction of a force?

Answer 7

the right-hand rule

Question 8

What do linear accelerators do?

Answer 8

use electric fields only to accelerate particles in a straight line

Question 9

What do cyclotron accelerators do?

Answer 9

use electric fields to accelerate particles and magnetic fields to change direction

Question 10

What do synchrotron accelerators do?

Answer 10

more modern versions of cyclotrons, use electric fields to accelerate particles and magnetic fields to change their direction
