Equ-Potential lab.pdf Work done can also be determined by considering movement across equipotentials. This can be written as: AW by you = q(Vp2 – VP1). VPi is the electric potential at point Pi. This tells us that the work done by you is dependent only on the magnitude and type (+ or -) of the electric charge you are trying to move, and the difference in electric potential from the ending point to the starting point. Both of these equations could yield positive or negative values for work. Positive work for you means that you (or some outside influence) are doing work against the field to move the charge. Negative work for you means that you aren’t doing any work and the particle moves the way the field would naturally push or pull the charge. 3) Use the equations above that determines work and your sketches (for electric fields and equipotentials) to state if each of the situations below would be + or - work: a) Moving a + charge from a point of higher electric potential to one of…
Consider a thin, uniformly charged rod of length L with total charge Q and test points A, a distance a from the center of the rod and B a distance b from the rod. Find the potential difference between A and B first by integrating the point source potential to find VA and VB and subtracting, and then by integrating the field. Compare the results in the limit of L>>(a and b). To test the far field limit, compare the appropriate result to the case where L is much less than both a and b. You may need to do this one numerically.

Two large charged plates of charge density ±18µC/m² face each other at a separation of 7 mm. Choose coordinate axes so that both plates are parallel to the xy plane, with the negatively charged plate located at z = 0 and the positively charged plate at z = +7 mm. Define potential so that potential at z = 0 is zero (V(z = 0) = 0). Hint a. Find the electric potential at following values of z: o potential at z = -7 mm: V(z = -7 mm) = o potential at z = +1 mm: V(z = +1 mm): = o potential at z = +7 mm: V(z = +7 mm) = = o potential at z = +9.2 mm: V(z = +9.2 mm) = V.

A charged ball is fired straight up, starting from a point at which the electric potential is +200 V. The equipotentials are equally spaced, as shown in the picture above, with successive lines in the picture being exactly 1.00 meter apart. This is done at the surface of the Earth, where the gravitational field has a value of g = 10.0 m/s2, directed straight down. The magnitude of the charge on the ball is 10 millicoulombs. Part (b) The ball has a mass of 200 grams. If the ball has a positive charge, what initial velocity must it have at the +200-V level for it to reach its maximum height at the +700-V level?_______ m/s)
