Need help with these two questions

How much work (in joules) is done in moving a charge of 2.5 uC a distance of 56 cm along an equipotential at 12 V? Do not include units with your answer. Question 6 1 pts cm 4- E 2 - B. 0 cm The field lines associated with a uniform electric field in a region of space are shown in the attached figure. Imagine drawing two equipotentials in the plane of the figure, one passing through point A and and one passing through point B. If the electric field is 350 N/C, how much does the potential change in going from A to B? Provide your answer in volts and use a positive value if it increases and a negative value if it decreases. Do not include units with your
