A) Maxwell
B) Hertz
C) Bose
D) Marconi
Correct Answer: A
Solution :
In 1865, James Clark Maxwell, an English scientist developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves. We \[{{U}_{f}}-{{U}_{i}}\] \[=9\times {{10}^{9}}\times {{g}_{1}}{{g}_{2}}\left[ \frac{1}{{{r}_{2}}}-\frac{1}{{{r}_{1}}} \right]\] \[=9\times {{10}^{9}}\times 12\times {{10}^{-6}}\times 8\times {{10}^{-6}}\] \[\left[ \frac{1}{4\times {{10}^{-2}}}-\frac{1}{10\times {{10}^{-2}}} \right]\]
