1. The problem statement
Consider the electron and the force on the electron is F=Cxj, where C is a positive constant. F, xj are vector?

Homework Equations



Consider the electron and the force on the electron is F=Cxj, where C is a positive constant. (F, xj are vectors)

a) The electron travels from the point (0, 0) to the point ( L , L ) along the straight line from (0, 0) to (0,L) and then along the straight line from (0,L) to ( L, L). What is the work done by the force F during this displacement?

b.)The electron travels from the point (0, 0) to the point ( L, L) along the straight line from (0, 0) to (L , 0) and then along the straight line from (L , 0) to (L ,L). What is the work done by the force F during this displacement?

c.)The electron travels from the point (0, 0) to the point (L ,L ) along the straight line from (0, 0) to (L ,L ). What is the work done by the force F during this displacement?

I do not recall doing a problem like this in class. Can anyone help me out?
