Suppose a unidirectional vector field E exists across an enclosed surface A as shown below. which among the following is/are true? The divergence volume integral value will only be equal to 0 if E is a uniform field. The divergence volume integral value will be positive if the magnitude of E is increasing along the positive z-hat direction. The divergence volume integral value will always be equal to 0. Only the top and bottom cylindrical phases have non-zero divergence surface integral values.
