= A 4.1 MC point charge is placed on the x-axis at the point X₁ -22.5 m. A second, 2.7-MC point Charge is placed on the x-axis at the point X₂ = 10.3m. What is the x-component of the net electric field (in N/C) at the origin? (Remember that vector components can be positive or negative) N/C

7. A-10 µC charge is located at the origin. What is the strength of the electric field at the position (x.y) = (-5.0cm, 5.0cm)?

Let q 1 = 2 μC, q2 = -4 μC, q3 = = +3 μC, q4 = -5 μC, q5 = +9 μC.a. What is the net force on q 5 ?b. What is the electric field at the location of q 5 due to the other 4 charges?c. What would be the force on q 5 if you changed it to 7 μC?

a. Determine the magnitude and direction of the electric field at point P, 20 cm away from charge Q = +10?C b. Two charges are lying on the horizontal axis and are 0.2m away from each other. 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
