The potential of the electric field produced by a point charge at any point (x, y, z) is given by \(y=3 x^{2}+5\), where x, y and z are in meter and V is in volt. The intensity of the electric field at \((-2,1,0)\) is
  1. + 17 Vm-1
  2. \(\text { — }\)17 Vm-1
  3. + 12 Vm-1
  4. \(\text { — }\)12 Vm-1

Answer

(D) — 12 Vm -1
