As given in the problem, for point Q, the radial line subtends an angle 60º with field direction. (this is assumed by me, because I feel there is typing error in the question). Hence it can be verified from figure point Q is below from the line of constant potential =589.0 V by [ 1 - (√3/2) ]×r, where r is the radius of sphere. Hence potential at Q is given by
VQ = 589.0+0.134×(0.8/2) = 589.536 V.
