The path of an electron, traveling at 3.7 × 104 meters/second, is making a right angle to a magnetic field. a single electron experiences a force of 2.2 × 10-15 newtons while in the field. what is the strength of the magnetic field? the value of q = -1.6 × 10-19 coulombs.

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.

the closer the planet is to the sun, the larger the gravity

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

its a circle not a square that's simple silly.
