10 Homework Then complete the attached worksheets: (Note: the above problems were designed to ensure you have the skills to solve the worksheet problems. It is imperative to your learning of the problem solving technique to do the above problems BEFORE attempting the worksheet problems. You are graded on both! Homework notebooks are graded.) CH‐24‐A‐1: For each of the equations below, 1) State what each term is in your own words … 2) What the units of each term are… 3) What is the general use of that equation in your own words? A.

The figure also shows vector superimposed on a coordinate axis. What is the potential VB at xB if the potential at xA is defined to be (a) 0, (b) ‐10 V, and (c) +10V ? Show all work : CH‐24‐A‐3: In the figure below, a charged particle (either an electron or a proton) is moving rightward between two parallel plates separated by d=9nm. The plate potentials are V1=‐45V and V2=‐62V. The particle is speeding up from an initial speed of 24km/s at the left plate. What is the speed of this particle as it reaches plate 2? Hint: You must determine which particle it is, before you can solve for the magnitude of Vf. Show all work: CH‐24‐A‐4: The Figure below shows a uniformly charged rod of length L and total charge Q. It also shows a point P a distance d away from the rod. Set up the integration to calculate the electric potential (V) at P due to the rodʹs charge. Your answer should not include !
