The charges are: ?1 =20?? ??? ?2 = −40??. Determine the magnitude and direction of the force on q1 by q2. c. An electron (q = -1.6 x 10-19 C) is initially at rest. At some time later, the electron accelerates due to a 5kV potential. Determine the change in electrical potential energy and final speed of the electron. Write down three examples of the use of electricity and magnetism in the medical field. For example, an automated external defibrillator (AED) consists of a capacitor to store electrical energy and electrode pads to deliver an electrical shock to your heart. As a result, an automated external defibrillator (AED) with CPRincreases the chances of restoring a victim’s heart rate after a sudden cardiac arrest. Use three of your ownexamples
