Final answer:
The problem seeks to find the electric charge, q₇₀, from given electric field strengths, but lacks sufficient context or data to perform the calculation. The usual approach is using the formula relating electric field strength to charge and distance, but without distance or a relation between the fields e₇₀ and e₇₁, the charge cannot be determined.
Step-by-step explanation:
The question at hand deals with the electric field and the electric charge of a particle. We're given the electric field strengths due to a charge at two different points, e₇₀ and e₇₁, with specific values for each. To find the charge at position 70, denoted as q₇₀, we would typically use the formula E = k * |q| / r², where E is the electric field strength, k is Coulomb's constant, |q| is the magnitude of the charge, and r is the distance from the charge to the point where the electric field is being measured.
However, without additional information such as the distance r or the means to relate e₇₀ and e₇₁ to derive q₇₀, the problem as stated does not provide enough data to calculate q₇₀. It seems that there might be missing information or context that is needed to properly calculate the charge. Please provide any additional details or information if available.
