Electrostatics 1. What is the force acting on an electron in an electric field of strength 2400Vm'1? (L0 3.2, L0 3.2) 2. What is the electric field strength between two parallel plates 5cm apart with a potential difference of 25V across them? (L0 3.1, L0 3.2) 3. Calculate the total charge on a ZSuF capacitor connected to a constant voltage of 100V in a d.c. circuit. How much energyr is stored in the capacitor? (L0 3.2, L0 3.3) 4. Calculate the total capacitance ofthree capacitors 30uF, ZOuF & 12uF connected in parallel across a d.c sunplv (L0 3.2, L0 3.3) 7. Calculate the total charge on the capacitors connected in series if the supply voltage is 500V. Sketch a circuit diagram and label this to show how the charges are located (L0 3.1, L0 3.2, L0 3.3)
