There is a uniform electrostatic filed in a region. The potential at various points on a small sphere centered at P, in the region, is found to vary between in the limits 589.0 V to 589.8 V. What is the potential at a point on the sphere whose radius vector makes an angle of \[60{}^\circ \]with the direction of the field?

• A. 589.5 V
• B. 589.2 V
• C. 589.4 V
• D. 589.6 V
