SUMMARY
The discussion focuses on calculating the electric field at point Z due to two charges, utilizing the formula epsilon = Fe/q. The participant initially miscalculated the electric field strength, arriving at 1.44 x 10^5 N/C instead of the correct value of 1.21 x 10^5 N/C. Key errors included confusion between sine and cosine functions for angle calculations and neglecting to square root the radius components. Ultimately, the participant corrected their approach by properly applying trigonometric functions and recognizing the relationship sin(180-theta) = sin(theta).
