Question: 1-8 U-Science-Gr6-Unit3-PBT-CBT (2020-21)
Spring 1 and Spring 2 are the same type of spring. Both springs were pushed or compressed into different positions and clamped into place.
Which spring has less potential energy?
O Spring 1
o Spring 2
O Spring 1 & Spring 2 have the same amount of energy.
You cannot tell unless you know what the springs are made of.

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
