Final answer:
The electric field at the origin can be calculated using the formula E₁ = (k * q₁) / r². However, the question does not provide the necessary information to calculate the electric field.
Step-by-step explanation:
The electric field at the origin can be calculated by using the formula:
$$E_1 = \frac{{k \cdot q_1}}{{r^2}}$$
where $k = 8.99 \times 10^9 \, \text{Nm}^2/\text{C}^2$ is the electrostatic constant, $q_1$ is the charge, and $r$ is the distance from the origin. Since the question does not provide the charge or distance, I am unable to calculate the electric field at the origin.
