22. The two long parallel filaments are at a distance d = 5 cm apart. On the threads are evenly distributed charges with a linear density τ1 = -5 nC / cm and τ2 = 10 nC / cm. To determine the electric field intensity E at a point remote from the first thread in the region r1 = 3 cm, at a second distance r2 = 4 cm.
