Electrostatics question

2025 · 2 Apr · Shift 1 · Q61

JEE MainPhysicsElectrostaticsMCQ+4 / −1
A point charge +q+q+q is placed at the origin. A second point charge +9q+9 q+9q is placed at (d,0,0\mathrm{d}, 0,0d,0,0) in Cartesian coordinate system. The point in between them where the electric field vanishes is:
  1. A
    (3d/4,0,0)(3 \mathrm{d} / 4,0,0)(3d/4,0,0)
  2. B
    (d/4,0,0)(\mathrm{d} / 4,0,0)(d/4,0,0)
  3. C
    (4d/3,0,0)(4 \mathrm{d} / 3,0,0)(4d/3,0,0)
  4. D
    (d/3,0,0)(\mathrm{d} / 3,0,0)(d/3,0,0)
