Lab #___- Concepts of Electric Field and Potential Difference

1. If the electric field intensity at a point is 1.0x10 5 N/C, the force on a 2.0x10 -6 C charge will be what? 2. What force will a proton experience in a uniform electric field whose strength is 2.00x10 5 N/C? 3. A positive charge of 7.0 x 10 -3 C experiences a 5.6 x 10 -2 N force when placed in a uniform electric field. What is the magnitude of the electric field intensity? 4. If 1.6x10 -12 J of energy is needed to move a charge through a potential difference of 1x10 7 volts, what is the magnitude of the charge? 5. Please draw electric field lines for the following situations: a. Sketch the electric field lines around a -1.0 C charge.
