1. The problem statement, all variables and given/known data A region of space has a uniform electric field of strength 10.0 V/m due east. A small metal sphere with charge of +50.0 nC is in the field. There sphere is moved at a constant speed by an external force 10 cm north, 50 cm east, 20 cm south, and 50 cm east. How much work was done in total by the applied force? 2. Relevant equations W = qEs 3. The attempt at a solution W = qE, so I tried to plug in the charges and electric field information. But I don’t know how to apply the fact that the electric field is directed due east. I can calculate the work if it were moved AGAINST the electric field, but I don’t know how to calculate it if it were moved in the same direction as the electric field or perpendicular to it, as in this case. The total work is just the sum of all the individual work required to move the charge each time. Thanks for your help!
