Please help!
A magnetic force of 3.2x10-12 N in the -z direction is acting on an electron
(q=-1.6x10-1°C) moving 1.0x10?m/s in the +y direction. What is the magnitude and
direction of the magnetic field?

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

what is the question because that is not a question.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

c) up

hope this
