Question

A 5.9 mC charge is accelerated by a potential difference of -7 V, which makes it go from a velocity of 4.1x103 m/s (left) to a velocity of 9.2x103 m/s (left). 

a) Since the particle was traveling to the left, and sped up, what was the direction of the acceleration of the charge, left or right?

b) What then must have been the direction of the force on the charge?

c) And then what must have been the direction of the electric field in the area?

d) Given that you know the electric field has to point from high potential to low potential, is the electron traveling from a low to a high potential, or is it traveling from a high to a low potential? (check that your answer matches with the sign of the given potential difference!)
