21. An electrostatic field is created by a uniformly charged spherical surface with a total charge of Q = 10 nC. Determine the potential difference between two points of this field lying at a distance of r1 = 10 cm and r2 = 20 cm from the center of the sphere (r2> r1> R, where R is the radius of the spherical surface).
