Which of the following charged particles will experience no magnetic force while in a magnetic field. a particle moving at a 90 degree angle to the magnetic field. a particle moving at a 45 degree angle to the magnetic field. a particle moving at a 180 degree angle to the magnetic field. a particle motion at a 270 degree angle to the magnetic field.

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
