A small metal sphere carrying a net charge of Q = -2.00 uC is held stationary by insulating supports. A second small metal sphere with a net charge of Q 2 + 7.80 uC and mass 1.50 g is is held 0.8 m away from the center of the first sphere. Assume the two

Two point charges lie along the y-axis. A charge of q1 = -8 µC is at y = 6.0 m, and a charge of q2 = -6 µC is at y = -4.0 m. Locate the point (other than infinity) at which the total electric field is zero. Need Help? Read It

An electric dipole consists of a particle with a charge of +5.4x106 C at the origin and a particle with a charge of -5.4 x 10-6 Con the x axis at x = 9.7x 10 m. Its dipole moment is: O 5.24e-8 O 5.24e-5 5.24e-7 0.00

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…

A conducting sphere of radius r1 = 0.46 m has a total charge of Q = 2.9 μC. A second uncharged conducting sphere of radius r2 = 0.23 m is then connected to the first by a thin conducting wire. The spheres are separated by a very large distance compared to their size. r1 = 0.46 mr2 = 0.23 mQ = 2.9 μC What is the total charge on sphere two, Q2 in coulombs?

A small metal sphere, carrying a net charge of q1=+2.80uc, is held in a stationary position by insulting supports. A second small metal sphere with a net charge of q2= -7.80uc and mass 1.50 g, is projected the word q1. When the two spheres are 0.800m apart, q2 is moving toward q1 with speed 22.0 m/s. Assume that the two spheres can be treated as point charges. You can ignore the force of gravity. (a) what is the speed of q2 when the spheres or 0.400 m apart? (b) how close does q2 get to q1?

The figure below shows a small, hollow, plastic ball hanging vertically from a thin, lightweight string. The ball has a mass of 6.30 g and a uniformly distributed charge of q₁ = 30.7 nC. Directly below it is a second ball with the same mass, but a charge of 92 -58.0 nC. (Assume this second ball is fixed in place.) The centers of the two plastic balls are a distance d = 2.00 cm apart. = 91 + 92 (a) What is the tension (in N) in the string? .10174 N Need Help? (b) The string will break if the tension in it exceeds 0.180 N. What is the smallest possible value of d (in cm) before the string breaks? 0.0339 The analysis is the same as in part (a), including the magnitude and direction of the gravitational and electric forces. Note that Coulomb's law depends on the square of the distance d. Use the threshold value of the tension to solve for d. cm Read It

Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a string & are in static equilibrium. The 39 kg red sphere has more charge than the 22 kg green sphere. The total charge magnitude on the spheres is 120 ?C & they have the same polarity. As a result the tension is 202.5 N & the centers of the spheres are 0.39 m apart. Find the charge magnitude on each sphere. Qred (bigger charge) = Qgreen (smaller charge) =
