37. Two long, thin-walled tubes of coaxial radii R1 = 2 cm and R2 = 4 cm charges are uniformly distributed along the length of a linear density τ1 = 1 nC / m and τ2 = 0,5 nC / m. The space between the tubes filled with hard rubber. Define E field intensity at points at distances of r1 = 1 cm, r2 = 3 cm, r3 = 5 cm. Plot the E of r.
