What is the electric potential

[From: ] [author: ] [Date: 11-09-04] [Hit: ]
V = q/(4*pi*epsilon*r)-V=kq/rv=9*10^9*0.004/0.......
What is the electric potential at a point 0.45 m away from a point charge of 4.0m C?

Used this formula but didn't get the correct answer, please help and please show work.

V = q/(4*pi*epsilon*r)

-
V=kq/r v=9*10^9*0.004/0.45 v=8*10^7volts
