Answer:
The electric field will be zero at x = ± ∞.
Explanation:
Suppose, A -2.0 nC charge and a +2.0 nC charge are located on the x-axis at x = -1.0 cm and x = +1.0 cm respectively.
We know that,
The electric field is
The electric field vector due to charge one
The electric field vector due to charge second
We need to calculate the electric field
Using formula of net electric field
Put the value into the formula
Put the value into the formula
If x = ∞, then the equation is be satisfied.
Hence, The electric field will be zero at x = ± ∞.
