2- Write a MATLAB code to visualize (2D) the electric field vector due to four equal point charge...
Three equal point charges, each with charge 1.10 , are placed at the vertices of an equilateral triangle whose sides are of length 0.350 . What is the electric potential energy of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.) Use = 8.85×10−12 for the permittivity of free space.
Three equal point charges, each with charge 1.20 μC , are placed at the vertices of an equilateral triangle whose sides are of length 0.700 m . What is the electric potential energy U of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.) Use ϵ0 = 8.85×10−12 C2N⋅m2 for the permittivity of free space.
can anyone help me figure out how fo write matlab code for these problems? BME 2013 Spring 2019 Exam 3 Matlab Review Sheet 1. Given the vector of patient body temperatures T (98.6, 102, 101, 99,98.9, 102.1, 100.3, 101.2, 98.4 97.6, 100] use conditional statements and loops to write a program that determines and displays (using the fprintf function) the number of patients with a fever and patients without a fever. The program must ask the user to input the...

When a single charge q is placed on one corner of a square, the electric field at the center of the square is F/q. If three other equal charges are placed on the other corners, the electric field at the center of the square due to these four equal charges is zero. Why is it zero? Show work and or explain.
I need matlab code of the following problem. 1. Plot the values of electric field around a positive charge in free space in two dimensions..... I need the code asap. please.
