Solve the all parts of given question:

Question: A high power cell phone tower radiates microwave power at a level of P=50W. The towers arrays are directional (not isotropic) and provide a gain G, of 17dB. So the effective power is P*G. (Note convert the dB factor to a ratio: Pout / Pin , before using this formula).

Part A: Calculate the Intensity (in units of W/m2) on the surface of a sphere of radius 100m. (The radiation is not isotropic, but the gain factor makes up for this).

Part B: Calculate the electric field (V/m-1) at this distance from the tower assuming a medium of refractive index n= 1.33 (water). Hence find the voltage induced across a brain sized object of around 25cm.

Having trouble with this physics question, can you please explain with the answer.
