Electrostatics Question 203
Question: Three charges each of magnitude q are placed at the corners of an equilateral triangle, the electrostatic force on the charge placed at the center is (each side of triangle is L) [DPMT 2002]
Options:
A) Zero
B) $ \frac{1}{4\pi {\varepsilon _{0}}}\frac{q^{2}}{L^{2}} $
C) $ \frac{1}{4\pi {\varepsilon _{0}}}\frac{3q^{2}}{L^{2}} $
D) $ \frac{1}{12\pi {\varepsilon _{0}}}\frac{q^{2}}{L^{2}} $
Show Answer
Answer:
Correct Answer: A
Solution:
Since $ |\overrightarrow{F _{A}}|=|\overrightarrow{F _{B}}|=|\overrightarrow{F _{C}}| $ and they are equally inclined with each other, so their resultant will be zero.
