Which of the following statements must be true for this case? No work is required to move the negative charge from point A to point B. Work is required to move the negative charge from point A to point B. Onone of the given choices The work done on the charge depends on the distance between A and B. The negative charge performs work in moving from point A to point B.Question 32 If the electrical potential in a region is constant, the electric field must be zero everywhere in that region. more information is needed True sometimes O True always False always @ none of the given choices
