Number
There are four charges, each with a magnitude of 2.38 μC. Two are positive and two are
negative. The charges are fixed to the corners of a 0.132-m square, one to a corner, in such a way
that the net force on any charge is directed toward the center of the square. Find the magnitude
of the net electrostatic force experienced by any charge.

- Question is attached, thank you.arrow_forwardTwo very small spheres are initially neutral and separated by a distance of 0.612 m. Suppose that 4.12 × 1013 electrons are removed from one sphere and placed on the other. (a) What is the magnitude of the electrostatic force that acts on each sphere? (b) Is the force attractive or repulsive?arrow_forwardEstimate the diameter of the Moon. During a total solar eclipse, the Moon passes in front of the Sun so that during “totality” their apparent sizes match and the Moon blocks light from the Sun shining on the Earth. a) What do you predict the size of the Moon would be if you were to use a pinhole in an aluminum holder, meter stick, and white paper screen to project light from the full Moon through a pinhole onto a screen that is one meter away from the pinhole? b) Describe in detail how you would use this apparatus and your knowledge of pinhole phenomena to estimate the diameter of the Moon. Assume that the distance between the Earth and the Moon is 250,000 miles.arrow_forward

Measurements and Linear Regression 1.1 Introduction The objective of this lab assignment is to represent measurement data in graphical form in order to illustrate experimental data and uncertainty visually. It is often convenient to represent experimental data graphically, not only for reporting results but also to compute or measure several physical parameters. For example, consider two physical quantities represented by x and y that are linearly related according to the algebraic relationship, y=mx+b, (1.1) where m is the slope of the line and b is the y-intercept. In order to assess the linearity between y and x, it is convenient to plot these quantities in a y versus x graph, as shown in Figure 1.1. Datapoints Line of regression Figure 1.1: Best fit line example. Once the data points are plotted, it is necessary to draw a "best fit line" or "regression line" that describes the data. A best fit line is a straight line that is the best approximation of the given set of data, and…arrow_forwardPlease help with Statistical Analysis table.
