Function: Pendulum in Electric Field

%% Function: Pendulum in Electric Field
% Can calculate the angle of deflection in degrees and radians of a
% pendulum in an electric field. If there is not a relative
% permittivity, Er should be 1. It should be noted that this is
% different than my paste " Pendulum in an Electric Field" which
% asks users for multiple inputs and will print outputs.


function [radians, degrees] = AnglePen(q,E,m,Er)
g = 9.81;            %[m/s^2] Acceleration due to gravity on earth
radians = atan((q*E/Er)/(m*g));
degrees = atand((q*E/Er)/(m*g))
end
