Help pls A point charge q is surrounded by a charge uniformly distributed in a spherical crust of radii R1 = R and R2 = 2R, concentric with the point charge. The potential at a point P distant 4R from the point charge is known to be zero.

As a function of q and R, it is requested:

1) Value of the charge Q distributed in the spherical crust and the density volumetric loading.

2) The electric field in the following areas:

zone A: 2R
zone B: R
zone C: 0

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
