As shown in figure , a charge q, = 1.33 µC is located at the origin and a charge q, = -6.10 µC is located at (0, 3. (b) A third charge 93 = 3.40 µC charge is brought from infinity to point P. 3.00 m 93

The work done by an external force to move a charge from point A to point B is 15x10^47. If the charge was started from rest and had a kinetic energy 4.82x10 KJ when it reached point B. What must be the potential difference between A and B? How far apart is point B from point A?

The figure below shows equipotential contours in the region of space surrounding two charged conductors. 15.0 V 10.0 V OV 30.0 V 35.0 V 45.0 V 20.0 V 25.0 V Find the work WAB in electron volts done by the electric force on a pr that moves from point A to point B. Similarly, find WAC, WAD, and W, (Assume the proton starts and stops at rest. Enter your answers in e' HINT (a) w AB ev (b) WAC ev (c) WAD eV

Three point charges q1 = +2.7µC, q2 = −3.4µC and q3 = −1.6µC initially are infinitely far apart. They are then brought together and placed at the corners of an equilateral triangle. Each side has a length of 40 cm. Determine the total electric potential energy of these group of charges The final answer should be Example: 0.06N or 6.0x10^-2 N must be expressed to 60x10^-3 N or 60mN
