I'm not sure if I have to get the velocity of ball a or ball b, or get them both and average, I just need help on this part of the problem.

Homework Statement k = 9 * 10^9 Sphere A of mass m = 0.0004 kg holds a positive charge qA = 3.0 10^-5 C and is fixed in place. Point P is d = 0.03 meters away from Sphere A. Sphere B is identical in mass to sphere A, but carries a charge of qB = 3.6 10^-5 C. Sphere B is brought from a...

So K' = 2K, right, because Q is proportional to KE.

Then the kinetic energy doesn't change?

If Q*C = K; then 2Q*C = 2K' So the increase in kinetic energy is K, correct me if I'm wrong.

Homework Statement A particle with a mass m and a charge Q is accelerated through a potential difference V, causing its kinetic energy to increase by an amount K. Another particle of mass m/5 and charge 2Q is accelerated through the same potential. How much kinetic energy does this second...

Yes, I found the force from Q1 to be 1350000, and the force from Q2 to be 1800000. I'm not sure what to do after this though.

Homework Statement Three charges are set in the plane of the page so that they form the vertices of a right triangle of lengths a = 3 meters, b = 4 meters, and c = 5 meters. The charges |Q1| = 2.40 10^-3 C and |Q2| = 1.80 10^-3 C have unknown sign. Charge q = -4. 10^-4 C has a total...

Homework Statement A cylinder has a base area of 0.016 m2 and is fitted with a piston that can freely move. Below the piston, the cylinder is filled with gas that has a pressure P1 = 106000 Pa, a volume V1 = 0.0014 m3, and a temperature of T1 = 0 ° C when in state 1. The gas is then...

Oh yes, I realized that, but I don't know where to go from there, what equations should I use.

Yes, I've studied it, but how does that apply here?

It is compressible, does that mean it stays the same throughout?

Homework Statement A house has a roof with an area of 220 m2. Wind blows over the top with a speed of 10 m/s. The density of air is 1.29 kg/m2. The air inside the house is stagnant. Point A is just inside the roof, and point B is outside the roof at the same height. (a) What is the...

Homework Statement Consider a hose that carries water (density = 1000 kg/m3) leads to a nozzle that is elevated h = 1.3 meters above the ground. The nozzle has a diameter d, and the hose has a diameter D = 5d. Water flows through the hose with a speed vH = 0.6 m/s. (a) What is the...
