Solve the all parts of given question:
Question: A uniform electric field has magnitude E and is directed in the negative x direction. The potential difference between point a (at x= 0.70m ) and point b (at x= 0.90m ) is 280V.
Part A: Calculate the value of E.
Part B: A negative point charge q=0.200 µC is moved from b to a. Calculate the work done on the point charge by the electric field.
