A spring with an unstrained length of 0.069 m and a spring constant of 1.6 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 5.2 × 10-3 kg and a net charge of +6.4 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 0.060 m. What is...

In a room that is 2.44 m high, a spring (unstrained length = 0.30 m) hangs from the ceiling. A board whose length is 1.36 m is attached to the free end of the spring. The board hangs straight down, so that its 1.36-m length is perpendicular to the floor. The weight of the board (196 N) stretches the spring so that the lower end of the board just extends to, but does not touch, the floor. What is the...

2.) A spring hangs vertically from the ceiling. Its natural length is 1.0 m. When a mass of 2.0 kg is attached to the spring, the spring's equilibrium length is 1.5 m. (a.) What is the spring constant k? The mass displaced vertically from equilibrium by 1.0 cm. (b.) What is the period of oscillation? (c.) What is the maximum speed of the mass? (d.) Suppose I wanted to maximize the oscillation amplitude by tapping on the mass. At what...

A tire swing of length L = 6.3 m hangs from a tree over the water. On a hot day, a swimmer uses the swing to jump into the lake, and afterward the swing oscillates as a simple pendulum. What is the period of this pendulum? Question options: 5.0 s 6.0 s none of these 3.1 s 4.3 s Question An electric field of magnitude 100. N/c points vertically downward near Earth's surface. What force does a free electron experience...
