• Explain how a particle may be suspended between two parallel plates.

• Solve simultaneous force equations.

• Calculate the charge on a particle suspended in an electric field.

• Define cathode and anode.

• Explain how a cathode ray is generated.

• Calculate a cathode ray's velocity.

• Describe how a cathode ray can be deflected.

• Explain how the size of a force between two charges can change using Coulomb's law.

• Describe how Coulomb's law is consistent with Newton's third law.

• Solve problems for the force between two charges using Coulomb's law.

Mahi Mō Te Rā/Tasks For Today

• Do your attendance for this lesson (just once even though it is a double period)

• Work on the sciPad pp251-256) OR the Education Perfect (Applications of Static Electricity) work

• Join the Google Meet in the first 20 minutes into each lesson if you need help with any of the work from yesterday or today. Type your question in the chat window.

• You can ask questions about today's work in the Google Meet at the start of our next lesson.
