Question

During a thunderstorm, some cows gather under a large tree. One cow stands facing directly toward the tree. Another cow stands at about the same distance from the tree, but it faces sideways (tangent to a circle centered on the tree). Which cow do you think is more likely to be killed if lightning strikes the tree?

Answer 1

The potential difference is more for cow A is,

(ΔV)A = 600 V – 200 V

          = 400 V

 

The potential difference is more for cow A is,

(ΔV)B = 400 V – 200 V

           = 200 V

 

The potential difference for cow A is 400V which is more than the cow B 200V.

 

Therefore, cow-A is more likely to be killed if lightning strikes the tree.

Therefore, cow-A is more likely to be killed if lightning strikes the tree.
