Advanced Physics Electric Potential 1. A uniform electric field of magnitude 41000 N/C points in the positive //x//-direction. Find the change in electric potential between the origin and the points **(a)** (0, 6.0 m), **(b)** (6.0 m, 0) and **(c)** (6.0 m, 6.0 m).

2. A parallel plate capacitor has plates separated by 0.75 mm. If the electric field between the plates has a magnitude of **(a) 12000000** V/M or **(b) 24000** N/C, what is the potential difference between the plates?

3. The electric potential 1.1 m from a point charge //q// is 28000 V. What is the value of //q?//
