Consider a sphere of radius R with charge density distributed as ρ (r ) = ≤ kr r R for = > 0 for r R .(a) Find the electric field at all points r.(b) Suppose the total charge on the sphere is 2e where e is the electron charge. Where can two protons be embedded such that the force on each of them is zero. Assume that the introduction of the proton does not alter the negative charge
Consider a sphere of radius R with charge density distributed as `ρ (r ) = kr ' for ' r le R` `ρ (r ) =0 ' for ' r > R` . (i) Find the electric field at all points r.(ii) Suppose the total charge on the sphere is 2e where e is the electron charge. Where can two protons be embedded such that the force on each of them is zero. Assume that the introduction of the proton does not alter the negative charge
If x + y = 0, then –y is known as the negative of x, where x and y are rational
0 is whole number but it is not a rational
The negative of the negative of any rational number is the number
