Fs = kx k=spring constant
x = displacement (stretch) of the spring
1. The staples in a stapler are pulled into position by a spring with a spring
constant of 100 N/m. When you close the stapler, the spring stretches 0.15 m
long. How much spring force does it exert on the staples?

Please help me

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
