Never, if the particle in the electric field has a charge.
Always, if the particle has no overall charge.
Explanation:
Electric field is usually given by:
#E# = Electric field strength (#NC^-1 or Vm^-1# )#V# = electric potential#d# = distance from the point charge (#m# )#F# = Electrostatic force (#N# )#Q_1 and Q_2# = charge on objects#1# and#2# (#C# )#r# = distance from point charge (#m# )#k# =#1/(4piepsilon_0)=8.99*10^9Nm^2C^-2# #epsilon_0# = permittivity of free space (#8.85*10^-12# #Fm^-1# )
However, depending on where the electric field is, a different value would be used instead of
Given
So, unless the particle in the electric field has no charge, then the electric field will always have a value.
