Place multiple charges of different magnitudes and polarities on the grid. Observe how the electric field lines interact and change as you add more charges. This experiment demonstrates the superposition principle, where the total electric field is the sum of the individual fields from each charge.

Experiment 4: Force Analysis

Place two charges of the same polarity near each other and observe the forces acting on them. Notice how the charges repel each other. Now, place two charges of opposite polarities and observe the attractive force. This experiment helps in understanding the principles of electrostatic forces.

💡 Note: When conducting experiments, pay close attention to the behavior of the field lines and forces. This will help you develop a deeper understanding of the underlying principles.
