A metаl sphere оf rаdius R≈2.0 cmR аpprоx 2.0 text{cm} is cоnnected to a +30.0 V+30.0 text{V} supply and allowed to reach electrostatic equilibrium. A voltmeter probe measures potential at points outside the sphere along a radial line: rr (cm) 2.0 3.0 4.0 5.0 6.0 8.0 10.0 VV (V) 30.0 20.1 15.2 12.1 10.1 7.6 6.1 (Here rr is the distance from the sphere’s center; just outside the surface r≈Rrapprox R.) Tasks (brief reasoning is fine): Model check: For an isolated charged sphere, V(r)∝1/rV(r)propto 1/r outside. Test this by evaluating V⋅rVcdot r for several rows—does it stay roughly constant? What does that imply about the model? Estimate RR or V ⁣sRV_{!s}R: Using your check in (1), estimate the product V ⁣sRV_{!s}R (surface potential ×times radius). Does it agree with the given V ⁣s=30.0 VV_{!s}=30.0 text{V} and R≈2.0 cmRapprox 2.0 text{cm}? Field at r=4.0 cmr=4.0 text{cm}: Use E(r)=∣dV/dr∣≈V ⁣sR/r2E(r)=big|mathrm{d}V/mathrm{d}rbig|approx V_{!s}R/r^{2} to estimate the electric field magnitude at r=4.0 cmr=4.0 text{cm}. Report in V/m and note the direction (radially inward or outward). Inside the conductor: What are the values of EE and VV inside the metal sphere (for r
