Q. In a television set, electrons are accelerated from rest through a potential difference of 19 kV. The electrons then pass through a 0.28 Tesla magnetic field that deflects them to the appropriate spot on the screen. What is the magnitude of the maximum magnetic force that an electron can experience?
Q. Two point charges and are held in place 4.50 apart. Another point charge -2.50 of mass 6.00 is initially located 3.00 from each of these charges and released from rest. You observe that the initial acceleration of -2.50 is 354 upward, parallel to the line connecting the two point charges.
