QUESTION 1 See the figure below. A uniform electric field exists in the region between two oppositely charged parallel plates. A particle with charge -7.40nC is placed in the electric field. Which of the following is true? + O A. The field goes to the left, the force on the particle goes to the left. O B. The field goes to the right, the force on the particle goes to the right. OC. The field goes to the left, the force on the particle goes to the right. O D. The field goes to the right, the force on the particle goes to the left. QUESTION 2 Following the previous question, if the electric field has a magnitude of 4.83 x 10³ N/C, the magnitude of the electric force on the particle is _N. Exponential format and 3 SF.

A particle of charge 2.0 x 10-8 C experiences an upward force of magnitude 1.5 x 10-6 N when it is placed at a particular point in space. Hint a. What is the electric field at that point? The electric field at that point is N/C. b. If a charge q = The force is in Select an answer direction with magnitude (Use "E notation" to give your answer in scientific notation, e.g. "3.14E-12" for 3.14 x 10-12 .) 3.0 x 107 -8 C is placed there, what is the force on it?

The net electric field at point A. a. For each part in practice question 1, find the net force on a -1.2 × 10-5 C charge placed at point A. b. How would your answer change if the sign of the charge from 2a at point A was changed? 3. Explain why the concept of a field was used to describe the force of gravity between two masses. 4. Give two reasons why the concept of a field is used again to describe the force between two charged objects.
