A particle launched between two fixed particles On the x axis, a particle A with charge 5uC is fixed at the origin and a particle B with charge -8uC is fixed at x=4m. Particle C has a mass of 700mg and a charge of -1uC: we place it at x=2m and we give it a speed of 15i m/s. Determine the modulus of its velocity when it is at x=3m

For this physics II problem its saids a 4.00 g ping pong ball is suspended from a light thread and given an electric charge. The ball is then placed in a uniform electrci field of magnitude 110,00N/C which causes the ball to swing out to an angle of 23 degrees. What is the sign and magnitude of the charge on the ball? The ball is angled to the right.    If you can break this down into step that would be great. Thanks!

Three point particles, each with a mass m and a charge of +5.0 nC, are placed at the vertices of an equilateral trian- gle with side length l fixed in place, but the third experiences an acceleration of 8.0 cm. Two of the particles are 17.4 m/s? immediately after being released from rest. What is the mass m of each particle? (Suppose that the particles are located in outer space so that you can ignore the effects of gravity.)

Two conducting spheres will attract each other with a force of 0.2 N when separated at 25 cm distance. Then these two balls are connected by a conducting wire so that charge balance occurs. After the conductor wire is released, it turns out that the two balls earlier will repel with a force of 0.05 N. What is the magnitude of the charge of the two balls that at first?

A positron has the charge and mass of an electron except that the charge is positive. A positron that is initially at rest at a distance of 2.0 nm away from a stationary carbon nucleus is then allowed to move freely. What will be the speed of the positron when it is infinitely far away from the carbon nucleus? Since the carbon nucleus is much more massive than the positron, it remains at rest. The mass and charge of a positron are m = 9.11 x 10-31 kg and e = 1.602 x 10-19 C, respectively, while the charge of a carbon nucleus is 6e.   a. 3.0 x 106 m/s  b. 2.4 x 106 m/s  c. 1.8 x 106 m/s  d. 3.6 x 106 m/s  e. 1.2 x 106 m/s

Assume that the charged particle is a proton of charge q=+e. The proton is released fromrest at the positive plate. In this case, each of the two oppositely charged plated which are d=2cm apart has a charge per unit area of σ=5μC/m2 . what is the speed of the protons as it strikes thesecond plate?

A positively charged particle Q1 = +25 nC is held fixed at the origin. A second charge Q2 of mass m = 9.5 μg is floating a distance d = 45 cm above charge Q1. The net force on Q2 is equal to zero. You may assume this system is close to the surface of the Earth.  Calculate the magnitude of Q2 in units of nanocoulombs.

a) A charge 4Q is located at x = −2l on the x-axis, and a charge Q is located at x = l on the x-axis. Q > 0. Near the origin, a positive test charge q with mass m undergoes small oscillations along the x-axis. What is the frequency ω of these oscillations? (Remember that if F = ma = −kx, then ω2 = k/m).

A hydrogen atom is made up of a proton of charge +Q = 1.6x10-19C and an eledron of charge -Q = 1.6x10-19C. The proton may be regarded as a point charge at r = 0 the center of the atom. The motion of the eledtron causes its charge to be "smeared ouť into a spherical distribution around the proton, so that the electron is equivalentto a charge per unitvolume of (7) =-(Q/ra?)e"lao, where a, = 5.29x10-11 m is called the Bohr radius. (a) Find the total amount of the hydrogen atom's charge that is endosed within a sphere with radius centered on the proton. (b) Find the eledricfield (magnitude and diredion) caused by the charge of the hydrogen atom as a fundtion of (c) Make a graph as a function of rof the ratio of the eledtricfield magnitude to the magnitude of the field due to the proton alone Set up: 1. 1. The charge distribution in this task is spherically symmetric, so you can solve it using Gauss's law. 2. The charge within a sphere of radius r indudes the proton charge Qplus the…

One particle has a mass of 3.71 x 10‍3 kg and a charge of +7.56 µC. A second particle has a mass of 7.17 x 103 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.177 m, the speed of the 3.71 x 103 kg-particle is 126 m/s. Find the initial separation between the particles.
