WBJEE · Physics · Oscillations
A unit negative charge with mass \(M\) resides at the mid-point of the straight line of length \(2 a\) adjoining two fixed charges of magnitude \(+Q\) each. If it is given a very small displacement \(x(x< < a)\) in a direction perpendicular to the straight line, it will
- A come back to its original position and stay there
- B execute oscillations with frequency
\[
\frac{1}{2 \pi} \sqrt{\frac{Q}{4 \pi \varepsilon_{0} M a^{3}}}
\] - C None of the above
- D execute oscillations with frequency
\[
\frac{1}{2 \pi} \sqrt{\frac{Q}{4 \pi \varepsilon_{0} M a^{2}}}
