Particle 1 has mass 3.00 g and charge +8.00 μC. Particle 2 has mass 6.00 g and the same charge. They are held at rest a distance d apart and then released, after which they fly apart. When the distance between them is 0.300 m, particle 2 has a speed of 64.0 m/s. What was the initial separation d? 0.781 cm 1.506 cm 1.485 cm 10.0 cm 0.675 cm

Two charged, parallel, flat conducting surfaces are spaced d = 1.1 cm apart and produce a potential difference ΔV = 715 V between them. An electron is projected from one surface directly toward the second. What is the initial speed of the electron if its comes to rest just at the second surface?

Before liquid crystal display LCD computer and television screens, the screens were cathode-ray tube CRTS, in which a bean of electrons was shot towards a Phosphorescent screen at high speed and deflected by electric fields in order to direct the beam to the right place on the screen so that it would form the picture. In a typical television, the speed of the electrons is 1 x10^8 m/s. If the television set is placed so that the CRT beam is horizontal heading east in a place where the earths magnetic field is 5×10^-5 and points horizontally northward what will be the magnetic force on the electron?

A proton is fired from very far away directly at a fixed particle with charge q = 1.90 x 10-18 C. If the initial speed of the proton is 1.9 x 105 m/s, what is its distance of closest approach to the fixed particle? The mass of a proton is 1.67 x 10-27 kg. X The correct answer is not zero. m Submit Answer

A particle 1 has a mass of 9.11 x 10^-31 kg and a charge of +1.60 x 10^-19 C. Suppose this particle 1 moves near a particle 2 that has a charge of +3.20 x 10^- 19 C and at all times remains at rest. When particle 1 is 1.4 x 10^-10 m away from particle 2, it is moving away with a speed of 3 x 10^6 m/s. What is the speed of particle 1 when it is a distance of 3.6 x 10^-10 m from particle 2? Answer in mm/s and with two decimal places.

= A point charge q₁ 9.1 µC is held fixed at 0.42 μC and a mass origin. A second point charge 2 3.2 x 104 kg is placed on the x-axis, 0.96 m from the origin. The second point charge is released at rest. What is its speed when it is 0.24 m from the origin? =

A parallel-plate capacitor has a charge Q and plate separation d, as shown below. We assume that the size of plates is much larger than the separation d. Each particle is initially at rest and then released, allowing it to accelerate.  Assuming each particle has the same mass, rank the speeds of the particles when they impact the left plate. 1. A parallel-plate capacitor has a charge Q and plate separation d, as shown below. We assume that the size of plates is much larger than the separation d.

A +5.6 C charged particle (m=2.0 kg) is placed 42 cm from a -3.7C stationary charge. If the particle starts from rest, how fast will it moving after it has traveled 24.0 cm. What is the change in potential energy, and what is the speed of the particle?

eV is a unit used in nuclear physics for the energy of particles. If an electron's charge is 1.6 * 10^-19 C, and its mass is 9.1 * 10^-31 kg, what is the speed of an electron with 1 eV kinetic energy to one significant figure? A) 600000 m/s (B) 5000000000 m/s (C) 2200 m/s D) 40000 m/s
