): Since the density varies with radius, integrate using a thin spherical shell element of radius and thickness

A smaller sphere (the size of the cavity) with a negative charge density −ρnegative rho placed at the location of the cavity. Step 2: Electric Field of a Solid Uniformly Charged Sphere Using Gauss's Law, the electric field E⃗modified cap E with right arrow above

r⃗1=a⃗+r⃗2⟹r⃗2=r⃗1−a⃗modified r with right arrow above sub 1 equals modified a with right arrow above plus modified r with right arrow above sub 2 ⟹ modified r with right arrow above sub 2 equals modified r with right arrow above sub 1 minus modified a with right arrow above Step 4: Superimpose the Fields at Point P The net electric field

If you are stuck, several resources offer detailed explanations: ): Since the density varies with radius, integrate

Static friction is generally greater than kinetic friction. For example, it is harder to start moving a heavy box than to keep it moving, due to the difference between static and kinetic friction.
