Will be zero for sure because of No resistor to both Gate and drain.
And if we calculate VDS =_IDRS but there is no value of ID.

Yeah, it should be zero.

I think its should be VDS is equal to VSS, of 13.51, since VDS = VD - VS but VD is equal to ZERO?

It should be zero. 13.5 - 9 * 1.5 = 0.
By getting 9a at the resistor using ohm's law. 13.5/1.5 = 9.

I didn't get anything.
Can you explain this properly again?

@Anand:
Initially the Vgs is 13.5 volts then it conducts and it becomes 0 volts because Vss will be 13.5 like Vgg but it will still conduct because saturation.
It looks like the drain is not having any resistor to +, ANAND, therefore IF it is connected to the + and not floating to nonsense the GATE and the DRAIN are connected to + and the voltage of 13.5 is more than enough to make conduct ANY mos-fet j-fet whatever and they usually when conduct have a voltage below 0, 1 volts so yeah, it should be zero.

@anand:formulae for Vgs and Id??
Anand said:

Why the hell would it be 0? Write the equations, find Vgs, calculate Id and subtract Id*Rs from 13.5. Answer is 3.8V

Yes..the answer should be zero.
