Singly ionized negative charges are accelerated from rest by applying a potential difference of AV before they enter a uniform magnetic field B (into the screen) as shown. L and R represent two fluorescent plates that record the location of a charged particle when it hits a plate. One such negative ion is accelerated from rest by a potential difference of 6.50 kV before entering the uniform magnetic field of 150 mT. Which plate (L or R) will it hit and at what distance d does it hit the fluorescent plate? Take mass of the ion to be 8.08 x 10-28 kg- R B.

You start out by driving 60 miles south in 4 hours and 18 minutes, and then you stop and park for a while. Finally you drive another 45 miles north in 2 hours and 33 minutes. The average velocity for your entire trip was 1.75 miles per hour to the south. How much time did you spend parked?     0 hours 51 minutes     8 hours 33 minutes     1 hours 42 minutes     3 hours 25 minutes
