Definition: In this task, you will be presented with a premise and a hypothesis sentence. Determine whether the hypothesis sentence entails (implies), contradicts (opposes), or is neutral with respect to the given premise sentence. Please answer with "Contradiction", "Neutral", or "Entailment".
Input: Premise: How to calculate electric flux<br>Know the formula for electric flux. [substeps] The electric flux through a surface a is equal to the dot product of the electric field and area vectors e and a. the dot product of two vectors is equal to the product of their respective magnitudes multiplied by the cosine of the angle between them. Determine the magnitude and direction of your electric field vector. <sep> Hypothesis: your electric field vector is not useful

Neutral
