📚Syllabus
• investigate and quantitatively derive and analyse the interaction between charged particles and uniform electric fields, including: (ACSPH083)
– electric field between parallel charged plates 𝐸=𝑉/𝑑
– acceleration of charged particles by the electric field 𝐹 ⃗_net=𝑚𝑎 ⃗, 𝐹 ⃗=𝑞𝐸 ⃗
– work done on the charge 𝑊=𝑞𝑉, 𝑊=𝑞𝐸𝑑, 𝐾=1/2 𝑚𝑣^2
• model qualitatively and quantitatively the trajectories of charged particles in electric fields and compare them with the trajectories of projectiles in a gravitational field
Forces and acceleration due to electric fields. What is a uniform electric field? What is the motion of a charge in a uniform electric field? Calculations of forces and acceleration due to electric fields.
