I = 1 amp, V = 2 volts, C = 5 F, and frequency = 10 Hz

1/2pi f c
1/2*3.14*10*5
0.003

Capacitive reactance
Xl=1/2pifc
then put the value
1/2*3.14*10*5=.003ohm Ans

If it is pure capacitive means:

Z = Xc = Impedance.

Then why we can't calculate Z = V/I.

Then answer is 2 ohm. Please clear if you have idea.

Xc = V/I. 2O HHM.

@Assd.

What is the meaning of HHM?

They have not mentioned purely capacitive.
@Dushyant Joshi.

They have just asked capacitive reactance.
so Xc=1/2*π*f*c.
