Two point charges lie on the I axis. A charge of +9.54 AC is at the origin, and a charge of -5.22 C is at I = 10.0 cm. At what position I would a third charge q3 be in equilibrium, provided that q3 is positive. Submit Answer Tries 0/32 At what position I would a third charge q3 be in equilibrium, provided that q3 is negative.

Subpart D please, thank you   Charged particles are floating in the following configuration in space. The particle in position 1 has a charge of 1.3x10-6C, and is located 55mm West ofposition 2. The particle in position 3 has a charge of -2.8x10-6C, and is located63mm East of position 2. The particle in position 4 has a charge of 3.1x10-6C, and is located 33mmSouth of location 2. d.Determine the total electric potential energy of the group of charges.

I do not know how to solve the attached phyiscs question.

You Answered Correct Answer A line of charge is placed along the negative x axis from x=-0.4m to x=0. The charge is uniformly distributed with linear charge density 3.06pC/m. A proton is released from rest at a point on the positive x axis 2.53m. When the proton has a speed of 472.1m/s, how far will it have moved (in m}? 1.0975 margin of error +/-1%

In the question above, charge q 2 is 2x10 -9C and charge q 1 has mass 0.23g.  The separation r is 2.5cm, and the angle θ is 15.9 degrees.  Find q 1(magnitude and sign, you don't need to enter a + for positive answers but you will need to enter a - if negative).  Note: the answer for this question is very small and using scientific notation will help.  This system uses E in place of x10 so for example to enter 3x10 -24 type 3E-24 in the answer box.

The uniformly charged straight wire in the figure has the length I, Find the field at point P, a perpendicular distance x from 0, if lambda (λ) is the charge per unit length. Express your answer in terms of , I, x, and appropriate constants. y 0 \r² = (x^² + y²) ² X P dEy dE dE

In the early 1900's Robert Millikan discovered the peculiar property that charge came in little packets, no smaller than e = 1.602 x 10-19 C -- he had measured the charge of the electron. Here's (roughly) how he did it.  He removed an electron from an initially neutral droplet of oil with diameter 0.5 ??μm. In a vacuum, he positioned the droplet between two metallic plates separated by 6 mm and fiddled with the potential (voltage) across the plates until the droplet would hover against the force of gravity. Droplets of this size with +e charge would hover, but only for a particular voltage (otherwise they would sink or rise).  Given the parameters stated here, and the fact that the density of the oil was 831 kg/m3, what was the voltage that made the droplets hover? (give your answer with 0.1 V precision)
