Electric Potential: Practice Problem & Solution
The variation of potential with distance r from a fixed point is as shown in the figure. The electric field at R = 5 m is :
Solution Explained:
To solve this problem, we apply the core principles of Electric Potential. Understanding the underlying formula is key to arriving at the correct answer below:
\[ E=-\frac{d V}{dr}= -(\frac{-5}{2})= 2.5 V/m \]
