Two point charges $-5 \mu \mathrm{C}$ and $+5 \mu \mathrm{C}$ are placed at $\mathrm{A}$ and $\mathrm{B}$ respectively on a straight line separated by $5 \mathrm{~cm}$. At a point $\mathrm{C}$ if the resultant field is parallel to the line joining the points $A$ and $B$ then

• Correct answer
  A

  $\mathrm{AC}=\mathrm{BC}$
• B

  $2 \mathrm{AC}=\mathrm{BC}$
• C

  $\mathrm{AC}=2 \mathrm{BC}$
• D

  $\mathrm{AC}=\frac{\mathrm{BC}}{3}$

Hence, the correct answer is option: 'A'.
