Aforce
f acts in the x - direction, its magnitude given by f = ax^2, where x is in meters and a =5.0n/m^2
. find the work done by this force as it acts on a particle moving from x = 0 to x = 6.0 m.

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
