Answer :

How to find the lightning shadow around a building
To determine the lightning shadow around a building, you can use the concept of a lightning protection sphere.
The lightning protection sphere is a hypothetical sphere that surrounds the building, and the radius of this sphere depends on the height of the building. When lightning strikes, it tends to preferentially strike the tallest object in the vicinity.
The goal of lightning protection systems is to intercept the lightning strike before it reaches the building.
The radius of the lightning protection sphere can be estimated using the following formula:
Radius of Lightning Protection Sphere = Height of Building x 2
The height of the building is 175 feet, so:
Radius = 175 feet x 2 = 350 feet
So, the correct option is:
Option 4: The lightning shadow is 350 feet in radius.
