impedance of an inductor = j*w*l, where j = i = imaginary number, w = frequency in radians, l = inductance

2000 = j*w*(250 x 10-3)

remove 'j' for simplicity (unless you are doing more advance bode plots!)

2000 * 10^3 = w*250

w = 8000 radians

radians = 2*pi * frequency in hertz, if the answer must be in hertz.
