यदि बिंदु \(\mathrm{P}\) पर \(\mathrm{Y}\) अक्ष के अनुदिश परिणामी विद्युत क्षेत्र शून्य है, तो \(\left|\frac{q_2}{q_3}\right|\) का अनुपात \(\frac{8}{5 \sqrt{x}}\), जहाँ \(\mathrm{x}=\) _______ है।

  1. A \(2\)
  2. B \(3\)
  3. C \(5\)
  4. D \(6\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(5\)

Step-by-step Solution

Detailed explanation

\(\frac{\mathrm{Kq}_2}{20} \cos \beta=\frac{\mathrm{Kq}_3}{25} \cos \theta\) \(\frac{\mathrm{Kq}_2}{20} \frac{4}{\sqrt{20}}=\frac{\mathrm{Kq}_3}{25} \frac{4}{\sqrt{25}}\) \(\frac{\mathrm{q}_2}{\mathrm{q}_3}=\frac{20}{25} \sqrt{\frac{20}{25}}=\frac{8}{5 \sqrt{\mathrm{x}}}\)…
