The nature of the point ?

V = potential at a point d distance away from a charge Q
           =  1/(4πε)  * Q / d²

=>    100 Volts = 9 * 10^9  * Q /0.1²
       =>  Q = 1.11 * 10⁻¹⁰  coulombs
As the potenial is positive.  the given charge is positive.    At the point P 0.1 m away from the isolated charge, the nature is :  positive.
