In the 1950s an experimental train that had a mass of 33200kg was powered across a level track by a jet that produced a thrust of 5.03*10^5n for a distance of 494m. find the work done on the train

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
