Four charges are at the corners of a square centered at the origin as follows:
q at (-a, +a); 2q at (+a, +a); -3q at (+a,-a); and 6q at (-a, -a).
A fifth charge +q is placed at the origin and released from rest.
A) Find its speed when it is a great distance from the origin if a = 1.2 m, q = 1.2 C, and its mass is 1.1 kg.

Idon't understand is there supposed to be a list or something if there is pm or add in under this message i will do my best to .

Hi. i believe this is called a scientific  theory.cheers!

Jenny and fred both play a long note on their trombones. a stationary observer hears the sound increasing and decreasing repeatedly in loudness. which of these must be true? the sound waves from the two trombones have slightly different frequencies.the sound waves from the two trombones have the same frequency.the sound waves from the two trombones have slightly different amplitudes.the sound waves from the two trombones have the same wavelength.the sound waves from the two trombones have slightly different velocities.  lolthe answer is          the sound waves from the two trombones have slightly different frequencies.
