A block having mass m and charge + Q is connected to an insulating spring having a force constant k . The block lies on a frictionless, insulating, horizontal track, and the system is immersed in a uniform electric field of magnitude E directed as shown in Figure P24.6. The block is released from rest when the spring is unstretched (at x = 0). We wish to show that the ensuing motion of the block is simple harmonic. (a) Consider the system of the block, the spring, and the electric field. Is this system isolated or nonisolated? (b) What kinds of potential energy exist within this system? (c) Call the initial configuration of the system that existing just as the block is released from rest. The final configuration is when the block momentarily comes to rest again. What is the value of x when the block comes to rest momentarily? (d) At some value of x we will call x = x 0 , the block has zero net force on it. What analysis model describes the particle in this situation? (c) What is the…
The electric field is zero everywhere except in the region 0≤x≤4.00 cm, where there is a uniform electric field of 110 N/C in the +y direction. A proton is moving in the +x direction with a speed of v = 1.00×10^6 m/s. When the proton passes through the region 0≤x≤4.00 cm, the electric field exerts a force on it.
1)When the x coordinate of the proton’s position is 4.00 cm, what is the x component of its velocity? (Express your answer to three significant figures.)
2)When the x coordinate of the proton’s position is 4.00 cm, what is the y component of its velocity?(Express your answer to three significant figures.)
3)When the x coordinate of its position equals 10.0 cm, what is the y component of its velocity? (Express your answer to three significant figures.)
A proton initially moves left to right long the x axis at a speed of 9,070 m/s. It moves into an electric field, which points in the negative x direction, and travels a distance of 0.7 m before coming to rest. If the proton's mass and charge are 1.67 × 10−27 kg and 1.60 × 10−19 C respectively, what is the magnitude of the electric field?
