Force on an electron at P = qE = (1.6X10^{-19} C)(3000 N/C) = 4.8X10^{-16} N to the left.

(opposite direction to E since electron is negative)

Pe of electron at P = qV = (-1.6X10^{-19})(-200 V) = +3.2X10^{-17} J

This also equals the electron's KE at infinity if released from rest at P.

It is also the work done against E to bring the electron from infinity to P.

All statements are correct
