An insulating rod having linear charge density λ = 40.0 μC/m and linear mass density μ = 0.100 kg/m is released from rest on a frictionless surface in a uniform electric field E = 100 V/m directed perpendicular to the rod (see Figure 7(a)). (i) Determine the speed of the rod after it has travelled 2.00 m. Figure 7(a) (Top View)
