 Homework Statement:

The equipotential surface passes through a point with field intensity electric 10 kV / m at a distance from a point charge generating a field of
r1 = 5 cm. At what distance from the field generating charge it belongs
carry out the second equipotential surface to make the potential difference
between these surfaces was equal to 100 V.
 Relevant Equations:
 E=V/d
Could somebody check my solution? I want to know is it correct.
