Question

Three charges $negative q subscript 1 end subscript comma plus q subscript 2 end subscript$ and $negative q subscript 3 end subscript$ are placed as shown in the figure. The x-component of the force on $negative q subscript 1 end subscript$ is proportional to

$\frac{q_{2}}{b^{2}} - \frac{q_{3}}{a^{2}} \sin θ$
$\frac{q_{2}}{b^{2}} - \frac{q_{3}}{a^{2}} \cos θ$
$\frac{q_{2}}{b^{2}} + \frac{q_{3}}{a^{2}} \sin θ$
$\frac{q_{2}}{b^{2}} + \frac{q_{3}}{a^{2}} \cos θ$

The correct answer is: $fraction numerator q subscript 2 end subscript over denominator b to the power of 2 end exponent end fraction plus fraction numerator q subscript 3 end subscript over denominator a to the power of 2 end exponent end fraction sin invisible function application theta$
