Question

Q#1, You have two initially uncharged dust particles. Each dust particle has a mass of 2.0 x 10-12 kg. They are each 1.0 x 10-4 m in diameter and are 0.001 m apart. You take 10 electrons off of one and put them onto the other. The two dust particles are now: attracted, repelled, neutral? Q.#2. How big is the force? Q #3. If you take another 10 electrons off the same particle and put them on the other, by what factor does the force between the 2 particles change? Q #4 If you now double the distance between the dust particles to 0.002m, by what factor does the force between them change?

Explanation / Answer

1)attracted 2)F=9x10^9x100x1.6^2x10^-38/(10^-6) =2.304x10^-19N 3)increases by 4 times as F is proportional to Q^2 4)decreases by 4 times as F is proportional to 1/r^2
