A spring with an unstrained length of 0.075 m and a spring constant of 2.2 N/m hangs vertically downward from the ceiling. A uniform electric field directed upward fills the region containing the spring. A sphere with a mass of 5.9 × 10-3 kg and a net charge of +7.2 μC is attached to the lower end of the spring. The spring is released slowly, until it reaches equilibrium. The equilibrium length of the spring is 0.063 m. What is the magnitude of the external electric field?

An unstrained horizontal spring has a length of 0.34 m and a spring constant of 203 N/m. Two small charged objects are attached to this spring, one at each end. The charges on the objects have equal magnitudes. Because of these charges, the spring stretches by 0.014 m relative to its unstrained length. Determine the possible algebraic signs and the magnitude of the charges. (a) the possible algebraic signs either: both positive or both negative both positive      both negative one...

A spring with constant k1 is attached vertically to the ceiling and a sphere of mass m1 hangs from the other end of the spring. Another spring, this one with constant k2 is attached vertically to the first sphere. Finally a second sphere (mass m2) is attached to the lower end of the second spring. Assuming that the spheres can only move vertically and using y1 and y2 as coordinates measured from the equilibrium position of each sphere, show that...

A small ball is attached to one end of a spring that has an unstrained length of 0.257 m. The spring is held by the other end, and the ball is whirled around in a horizontal circle at a speed of 3.15 m/s. The spring remains nearly parallel to the ground during the motion and is observed to stretch by 0.0138 m. By how much would the spring stretch if it were attached to the ceiling and the ball allowed...

A mass hangs vertically from a spring that is attached to the ceiling, and oscillates. If the kinetic energy of the mass is decreasing, what must be true about the mass's motion? The mass must be moving towards the equilibrium position. The mass must be moving upward. The mass must be moving away from the equilibrium position. The mass must be moving downward.

A sphere is attached to a vertical spring of constant k = 11,990 N/m. As the sphere is allowed to hang from the spring, it also is partially submerged in water, where 60% of its volume is underwater. When the sphere is in equilibrium, it has displaced the spring by 10.0 cm from its relaxed length. The density of the sphere is 4250 kg/m3. (a) Has the spring stretched or compressed? Explain. (b) What is the radius of the sphere?
