Calculate the magnitude of the net electric field at the origin due to these two point charges.?3) A point charge q1=-4.00nC is at the point x=0.60m, y=0.80m , and a second point charge q2=+6.00nC is at the point x=0.60m , y=0. A) Calculate the magnitude of the net electric field at the origin due to these two point charges. B) Calculate the direction of the net electric field at the origin due to these two point charges. (clockwise from +-x axis)

Explanation:

= Distance of from origin =

= Distance of from origin =

k = Coulomb constant =

Electric field is given by

The charge is on the x axis itself and it is pointing towards the origin (left side) so the sign will be negative

Resultant electric field

Magnitude of electric field is given by

Magnitude of the net electric field is

Direction is given by

From the -x axis

The direction of the net magnetic field is

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
