Question

True or False

When a charge is moved from point A to point B in E field, the work done by the electric force and the associated potential energy change depend on not only the initial and final locations, but also the path taken.

Answer 1

Step-by-step explanation:

The work of the electric force does not depend on the trajectory or the path taken. Regardless of trajectory a and b we have the following

Vide picture

`W_(ab) = (K Q q)/(R_(a) ) (K Q q)/(R_(b) )`

Wab: Work

K: coulomb constant (9·109 N·m2/C2)

Ra,Rb: distances

Qq: electric charges
