A proton follows the path shown in (Figure 1). Its initial speed is v0 = 2.9×10^6 m/s. Part A What is the proton’s speed as it passes through point P? Express your answer to two significant figures and include the appropriate units.
Question 1 Two point charges of equal magnitude are 2.6cm apart. At the midpoint of the line connecting them, their combined electric field has a magnitude of 114NC. Find the magnitudes of the two charges. (NOTE: Enter your answer in picocoulombs, pC.) Question 2 Four point charges, each of magnitude are located at the corners […]
Yalda’s Notes: My Notes: Example Calculate the work done in the moving this test charge the distance r Coulomb’s Law (for point charge) Potential Energy Example 2 So, here, Q’s potential energy changed by “Electric Potential” Then we can write Example (Capacitor) Calculate the […]
Question 1 Two identical negative charges are located on the y-axis, at y = +4m and y = -4m. A positive charge of 0.25C is placed on the x-axis at x = 2m. What direction does the net force on the proton point? Select one: A. Along the -x-axis B. At a 45 degree angle […]
Energy Is capacity to do work and/or generate heat through molecular motion. Key terms Work A force is said to do work if, when acting on a body, there is a displacement of the point of application in the direction of the force. For example, when a ball is held above the ground and then […]
At one point in space, the electric potential energy of a 20 nC charge is 56 μJ. Part A What is the electric potential at this point? Express your answer to two significant figures and include the appropriate units. Part B If a 25 nC charge were placed at this point, what would its electric […]
A 15 nC charge is moved from a point where V = 210 V to a point where V = -30 V. Part A How much work is done by the force that moves the charge? Express your answer to two significant figures and include the appropriate units.
