A uniformly charged, straight filament 6.70 m in length has a total positive charge of 2.00 µC. An uncharged cardboard cylinder 1.90 cm in length and 10.0 cm in radius surrounds the filament at its center, with the filament as the axis of the cylinder. (a) Using reasonable approximations, find the electric field at the surface of the cylinder. (b)Using reasonable approximations, find the total electric flux through the cylinder.

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

0.11 m/s and 0.28 m/s should be correct

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
