	1. ~~Set Up the Torsion Balance~~:
	~~- Attach~~ the ~~smaller spheres to each end of the rod~~.		1. Sample Preparation: Prepare the KBr samples for testing. This may involve grinding KBr into a fine powder and pressing it into a pellet.
	~~- Suspend the rod horizontally from its center using the torsion wire. The wire should be attached securely to~~ a ~~stable mount~~.
	~~- Attach the mirror to the wire just below the mount.~~		2. Electrode Setup: Set up the two-electrode system. One electrode is placed on either side of the KBr sample.
	2. ~~Prepare the Large Spheres~~:
	~~- Position the larger spheres near the smaller ones.~~		3. Impedance Measurement: Connect the KBr sample to the EIS system. Apply a small perturbation signal, and measure the impedance over a range of frequencies.
	3. Set Up the ~~Laser and Photodiode Array:~~
	- ~~Position the laser so that it shines~~ on the ~~mirror~~.		4. Data Collection: Record the impedance data at each frequency.
	~~- Set up the photodiode array at an appropriate distance so that it can detect the laser light reflected from the mirror.~~
	4. ~~Calibrate the Photodiode Array~~:		5. Data Analysis: Analyze the collected data using appropriate software or mathematical models. This includes creating Nyquist or Bode plots to visualize the data and fitting the data to an equivalent circuit model.
	~~- Shine~~ the ~~laser on each photodiode in~~ the ~~array~~ and ~~record~~ the ~~output. This will give you~~ a ~~calibration curve that you can use to convert photodiode signals into angles~~ of ~~rotation~~.
	5. ~~Perform the Experiment~~:
	~~- Carefully move the larger spheres closer to the smaller ones. The gravitational attraction will cause the rod to twist, turning the mirror and shifting the laser spot on the photodiode array.~~
	- Record the ~~photodiode output~~ at ~~regular intervals~~.
	6. Data Analysis:
	~~- Use your calibration curve to convert~~ the ~~photodiode signals into angles of rotation~~.
	~~- Calculate the gravitational constant using the observed rotation,~~ the ~~known mass of the spheres,~~ and the ~~properties of the torsion wire~~.

==Procedure==
1. Set Up the Torsion Balance:
- Attach the smaller spheres to each end of the rod.
- Suspend the rod horizontally from its center using the torsion wire. The wire should be attached securely to a stable mount.
- Attach the mirror to the wire just below the mount.
2. Prepare the Large Spheres:
- Position the larger spheres near the smaller ones.
3. Set Up the Laser and Photodiode Array:
- Position the laser so that it shines on the mirror.
- Set up the photodiode array at an appropriate distance so that it can detect the laser light reflected from the mirror.
4. Calibrate the Photodiode Array:
- Shine the laser on each photodiode in the array and record the output. This will give you a calibration curve that you can use to convert photodiode signals into angles of rotation.
5. Perform the Experiment:
- Carefully move the larger spheres closer to the smaller ones. The gravitational attraction will cause the rod to twist, turning the mirror and shifting the laser spot on the photodiode array.
- Record the photodiode output at regular intervals.
6. Data Analysis:
- Use your calibration curve to convert the photodiode signals into angles of rotation.
- Calculate the gravitational constant using the observed rotation, the known mass of the spheres, and the properties of the torsion wire.
