A charged particle is moving in a uniform, constant magnetic field. Which one of the following statements concerning the magnetic force exerted on the particle is false It does no work on the particle. It increases the speed of the particle. It changes the velocity of the particle. It can act only on a particle in motion. It does not...

Using magnetic and electric fields, you want to create a spectrometer to sort isotopes of hydrogen ions. A stream of 1H, 2 H+, and > H+ are accelerated to 2.00x105 m/s and launched into a velocity selector in a region where you can establish a uniform magnetic field with a strength of 240 mt. What electric field will you need...

When at rest, a proton experiences a net electromagnetic force of magnitude 8.3×10−13 N pointing in the positive xdirection. When the proton moves with a speed of 1.8×106 m/s in the positive y direction, the net electromagnetic force on it decreases in magnitude to 7.3×10−13 N , still pointing in the positive x direction. You may want to review(Pages 773...

Im kinda lost in this sample problem im trying to study..
could someone pls clarify my questuon i wrote in green..
My question is why they used that formula or can u relate that
to the formula i shown to u from my book. Whyvthey ignore that part
pf the formula for this problem??
