### Problem Description

**Beads C and D**

- Two 2.4-mm-diameter beads, C and D, are 12 mm apart, measured between their centers.
- Bead C has:
  - Mass: 1.0 g
  - Charge: 2.0 nC
- Bead D has:
  - Mass: 1.7 g
  - Charge: -1.0 nC

**Assumption**: The excess charge is distributed uniformly on each bead at all times.

### Part A

**Question**: If the beads are released from rest, what is the speed \( v_C \) of C at the instant the beads collide?

- **Instructions**: Express your answer with the appropriate units.
- **Interface**:
  - Input box for value and units.
  - Option to view available hints.
  - Submit button for answer.
  - Feedback shows "Incorrect; Try Again; 14 attempts remaining."

### Part B

**Question**: What is the speed \( v_D \) of D at the instant the beads collide?

- **Instructions**: Express your answer with the appropriate units.
- **Interface**:
  - Input box for value and units.
  - Option to view available hints.
  - Submit button for answer.

**Note**: The scenario involves physics concepts such as electrostatic forces and motion. Ensure calculations consider the properties of charges, masses, and distances.
