I am trying to sketch the negative waveform of an OPAMP over here.

I am not sure how to proceed with this as I have usually seen OPAMP with dual power supply. But this one have +9V and ground.
My thinking to go about this problem :

I am not sure how to proceed with this as I have usually seen OPAMP with dual power supply. But this one have +9V and ground.
My thinking to go about this problem :
- The voltage level at the positive terminal of OPAMP is +4.5V
- So, the voltage at Vout would also be +4.5V due to the 100k between between +ve and Vout
- As +4.5V is present at Vout, the 10nF capacitor which is connected to ground gets charged.
- As it gets charged to 4.5V, the output will will become 0V?
- So, the output will go to 0V?
