Question

Answer all questions Two parallel plates at -50kV and 100kV have separation 35cm. Calculate the following for a proton placed between the plates: AC1.1 a) The electric field strength between the plates b) The force experienced by the proton c) The energy required to move the proton from the surface of the negative plate to the surface of the positive plate. Inside a CRT television there is a uniform electric field between two plates at OV and 2.2kV. The plates are 8cm apart. Q2 AC1.2 a) Sketch the electric field pattern between these two plates b) Calculate the electric field strength between the plates and label your diagram c) Sketch the equipotential lines between the plates d) Calculate the position where electric potential is equal to 550 JC. Draw and label this equipotential line on your diagram Calculate the following for this circuit: 270 0 Q3 AC2.1 120nF 3.2uF 50nF a) The equivalent capacitance of the two capacitors in series b) The equivalent capacitance of this capacitor network c) The maximum charge that can be stored in this capacitor network d) The maximum energy that can be stored in the smallest capacitor
