Problem 3.35 a solid sphere, radius r, is centered at the origin. the "northern" hemisphere carries a uniform charge density rho0, and the "southern" hemisphere a uniform charge density −rho0. find the approximate field e(r,θ) for points far from the sphere (r ≫ r).

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
