Question Three charges  \( 4 q, \mathrm{Q} \) and \( q \) are in a straight line in the position of \( \mathrm{O}, l / 2 \) and \( l \) respectively. The resultant force on \( q \) will be zero, if \( Q \) is
(A) \( -q \)
(B) \( -2 q \)
(C) \( -\frac{q}{2} \)
(D) \( 4 q \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
