Two Concentric Conducting Spherical Shells Produce a Radially Outward Electric

question 9

Short Answer

Two concentric conducting spherical shells produce a radially outward electric field of magnitude 49,000 N/C at a point 4.10 m from the center of the shells.The outer surface of the larger shell has a radius of 3.75 m.If the inner shell contains an excess charge of -5.30 μC,find the amount of charge on the outer surface of the larger shell.
(k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²)

Definitions:

Fixed Production Costs

Costs that do not change with the level of production, such as rent, insurance, and salaries.

Variable Production Costs

Costs that change in proportion to the level of production activity, such as raw materials and direct labor.

Variable Costing

A costing method that includes only variable production costs in the cost of goods sold and treats fixed overhead as a period expense.

Absorption Costing

A cost calculation method in accounting that adds all expenses related to manufacturing—direct materials, direct labor, and both fixed and variable overhead—into the final cost of a product.
