Hi everyone! I'm new in here. Recently I bought a movement monitor which detects micro movement. If the sensor does not detect a movement in 20 seconds, the build-in speaker will beep until the sensor detects a movement. I'm using it for my project and I have a question about ...

A charge, q1, of +4.4 micro-coulombs and another unknown charge, q2, are surrounded by a surface. The total flux through the surface is -9.2 x 106 (N m2)/C. These charges are now placed on the x axis. q1 is placed at x = 0, and q2 is placed at x = +114.51 cm. What is the ...
