SATHEE: Electrostatics Question 375

Electrostatics Question 375

Question: Equal charges $q$ are placed at the vertices $A$ and $B$ of an equilateral triangle $A B C$ of side $a$ . The magnitude of electric field at the point $C$ is [MP PMT 1997]

Options:

A) $\frac{q}{4 π ε_{0} a^{2}}$

B) $\frac{\sqrt{2} q}{4 π ε_{0} a^{2}}$

C) $\frac{\sqrt{3} q}{4 π ε_{0} a^{2}}$

D) $\frac{q}{2 π ε_{0} a^{2}}$

Show Answer

Answer:

Correct Answer: C

Solution:

$| E_{A} | = | E_{B} | = k . \frac{q}{a^{2}}$

So, $E_{n e t} = \sqrt{E_{A}^{2} + E_{B}^{2} + 2 E_{A} E_{B} \cos 60^{o}}$ $= \frac{\sqrt{3} k . q}{a^{2}}$

therefore $E_{n e t} = \frac{\sqrt{3} q}{4 π ε_{0} a^{2}}$
