    Easy Electical potential problem i cant do

    hey all here's my problem two spherical drops of mercury have a charge of 1.0nC and a potential of 300V at the surface. the two drops merge to form a single drop. what is the potential at the surface of the new drop? thx anyone for there help

    How Do You Solve a Proton's Orbit and Electric Field Problems?

    Hey ppl! anyone who can help me with this i will be so grateful! I've been stuck on it for 2 days(dumbarse ) thx! 1) A proton orbits a long chared wire, making 1.0x10^6 revolutions per second. The radius of the orbit is 1.0cm. What is the wire's linear charge density? 2) Show that the on...

    What Do p and l Represent in the Resistance Formula R = pl/A?

    from my experience with this equation(electronic subject) we had "l" in cm, but that was because we had "p" in ohm.cm for example R = pl/A ----> ohms = [(ohms.cm)(cm)]/cm(^2)

    What Do p and l Represent in the Resistance Formula R = pl/A?

    p is the resistivity of a material(ohms.cm). Every material normally has a set value for it. l is the length of the material.

    Need help with electric field questions thx

    k thx, just checking I am on the right track, i found the force by F=(mv^2)r. then by using E = F/q (q = 1.6x10^-19), but this is where I am stuck any more pointers please? thanks again

    What is the RC time constant and how do you determine it through an experiment?

    Hey there! I've just currently done a electronics lab on testing the time constant(RC) of capacitors in networks. Your lab seems to be quite a bit more advanced compared to mine, but you can calculate the time constant by using method for a voltage vs time graph. the 63%37% method. I have no...
