Question

Two point charges +Q and -2Q are fixed on the x-axis at positions ‘a’ and ‘2a’ from origin respectively. At what positions on the axis, the resultant electric field is zero.​

Answer 1

Answer:

ull Point Two point charges (+Q) and (-20) are fixed on the X-axis at positions a and 2a from origin respectively. At what positions on the axis, the resultant electric field is zero (a) Only x = V2a (b) Only x = -2a (c) Both x = 1/2a (d) x = only 3a.
