“…We followed the procedure for charging two short pieces of Scotch Magic 3 M transparent tape as described in [15,16]. For this purpose, two identical pieces of transparent tape of length ∈ l (5, 15) cm were cut, one of them (called 'bottom' (B)) was placed with the sticky side on a table and the other (called 'top' (T)) stacked on top of it with its sticky side towards the slick side of the first tape (see figure 1(a)).…”

Despite the widespread use of the charged tape method to demonstrate electrostatic interaction and the advances in affordable sensors that can directly measure electric charges, there is no detailed analysis of a quantitative model for such experiments. As a result, we present two different theoretical approaches that allowed us to quantitatively estimate the amount of electric charge present on transparent tape. Our first model assumed that the entire electric charge was concentrated at the center of mass of the tape and gave a simple algebraic solution, which came close to the order of magnitude of the actual electric charge measured with a PASCO charge sensor. Our second model approximated the sticky tape as a linear uniformly charged object. The estimated electric charge based on the uniform charge density model is closer to the measured value of electric charge than the value found by approximating each piece of tape as a point charge. Based on the statistical test, the experiments did not support the predictions of the point charge model. At the same time, the statistical test validated the uniform charge density model with a p-value of 0.01.

Electrification by rubbing different materials is a well-known phenomenon with a history that began more than five centuries B.C. ago. However, simple experiments can lead to contradictory or inconsistent results, and the history of this phenomena is plagued with non-intuitive results. For example, triboelectric charging by rubbing identical materials is possible. In this work we want to highlight some historical aspects of triboelectricity that could enrich the discussion of electrostatics in an undergraduate physics course. We will focus on the effect of strain on the triboelectric properties of a sample, which we think is not well known to physics teachers. We will show that it is possible to obtain robust polarities by rubbing identical rubber balloons of different radii and we will also show that this charging method can be very useful in introductory physics courses.
