Along straight wire carries a current of 50 a. an electron, traveling at1.0×107m/s, is 5.0 cm from the wire. what is the magnitude of the magnetic force on the electron if the electron velocity is directed (a) toward the wire, (b) parallel to the wire in the direction of the current, and (c) perpendicular to the two directions defined by (a) and (b)?

Recall, The magnetic field on a electron in a wire, Bₓ = (µ₀ I)/(2πr)

Note: Magnetic force direction is at right angles to electron motion.

Magnetic force, F = q * v * Bₓ

Substituting Bₓ into F, we have

F = q * v * Bₓ = (q * v * µ₀* I)/(2π r) = (1.6 x 10⁻¹⁹ x 1.0 x 10⁷ x 4π x 10⁻⁷ x 50)/( 2π x 5 x 10⁻²) = 3.2 x 10⁻¹⁶ N

a) Hence, the magnitude of the magnetic force on the electron if the electron velocity is directed (a) toward the wire is 3.2 x 10⁻¹⁶ N  and opposite the current

b) Hence, the magnitude of the magnetic force on the electron if the electron velocity is directed (b) parallel to the wire in the direction of the current is 3.2 x 10⁻¹⁶ N  and away from the wire.

c) Hence, the magnitude of the magnetic forces on the electrons if the electron velocity is perpendicular to the two directions defined by (a) and (b) is 3.2 x 10⁻¹⁶ N  and (a) direction - opposite the current, (b) same direction as current.

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.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
