Useful data
Electron charge e = 1.60 10 19 C Proton charge +e = 1.60 10 19 C Electron mass me = 9.11 1031 kg Electric force constant k = 9.0 10 9 Nm2 /C2 Permittivity of free space 0 = 8.85 1012 C2 /Nm2 1. An object has a total electrical charge of +1.2 C. (a) Does the object have excess electrons, or a shortage of electrons? (b) How many electrons? 2. Charges of +1.0 C, 2.0 C, and +3.0 C are located along a straight line, at x = 0.50 m, x = 0.10 m, and x = 0.30 m respectively. What is the force acting on each charge? 3. A small uniformly charged sphere has a total charge of 1.4 10 8 C. (a) What is the electric eld at a point 5.0 mm away from the sphere? (b) What force would act on a point charge of 1.0 10 9 C at this point? 4. Two charges (A and B) are located 5.0 cm away from point P.

P
(a) What electric eld is produced at P by charge A? (b) What electric eld is produced at P by charge B? (c) What is the total electric eld at P? 5. A long, uniformly charged wire has a linear charge density = 5.0 C/m. (a) What is the electric eld at a point 3.0 cm away from the wire? (b) What would the acceleration of an electron at this point be? 6. ADVANCED Point charges of 1.0 C and 4.0 C are 10 cm apart. At what point is the electric eld equal to zero?

7. Two uniformly charged plates, with charges of + Q and Q, are 2.0 cm apart, and have a difference potential of 3,000 V between them. The electric eld between the two plates can be assumed to be uniform. (a) What is the magnitude of the electric eld betweeen the plates? What is the direction of the electric eld? (b) An electron is ejected by the negatively-charged plate into the space between the plates. What will happen to the electron? (c) How much work is done on the electron by the eld? (d) If the initial speed of the electron is zero, what is its nal velocity? (e) ADVANCED What is the charge density on each plate? (ie = Q/ A) Dont forget that there are two plates! 8. Draw electric eld diagrams for the following cases: (a) Two identical positive point charges near each other (b) A positive and negative point charge of equal magnitude near each other (c) A positive and negative point charge of unequal magnitude near each other
