Academics

1. A man of 50.0 kg mass is in equilibrium among two parallel plates. The man is charged up to + 130. mC of charge. The plates are 1.75 meters apart.

1. Draw a Free Body Diagram of the man. Hint: He is like a giant oil drop.

2. What must be the value of the electric force to keep him suspended among the plates?

3. What is the value of the electric field among the plates?

4. What must be the obvious direction of the electric force?

5. Is the top plate positive or negative?

6. What is the potential difference among the plates?

7. If the area of one plate is 20.0 m², what is the charge on one of the plates?

2. An electron initially at rest is accelerated among two parallel plates 2.000 cm apart. The area among the plates is in a vacuum. The potential dissimilarity across the plates is 300.0 V.

1. What is the electric field among the plates?

2. What is the electric force on the electron among the plates?

3. What kinetic energy does the electron have when it hits the positive plate?

4. If the plates have an area of 400.0mm², what is the capacitance of these plates?
