Athin plastic rod of length 2.5 m is rubbed all over with wool, and acquires a charge of 75 nc, distributed uniformly over its surface. calculate the magnitude of the electric field due to the rod at a location 7 cm from the midpoint of the rod. do the calculation two ways, first using the exact formula for a rod of any length, and second using the approximate formula for a long rod.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
