Solving a problem in physics section 68 point 80 electr

80. The electric field is created by a long cylinder of radius R = 1 cm uniformly charged with a linear density of τ = 20 nC / m. Determine the potential difference of two points of this field located at distances r1 = 0.5 cm and r2 = 2 cm from the surface of the cylinder in its middle part.
