Ch 25: The Electric Potential
Problem 1
The electric field strength is 50,000 N/C inside a parallel-plate capacitor with a 2.0 mm spacing. A proton is released from rest at the positive plate. What is the proton's speed when it reaches the negative plate?
Problem 4
An electron is released from rest at the center of a parallel-plate capacitor that has a 1.0 mm spacing. The electron then strikes one of the plates with a speed of 1.5×106 m/s. What is the electric field strength inside the capacitor?
Problem 5
What is the electric potential energy of the group of charges in FIGURE EX25.5?
