Ground voltage!!

If that is true, then you have a discontinuity somewhere between neutral and earth ground.  Could be anywhere all the way back to the circuit breaker box for your apartment building.  Or could be local.  You might call it to the attention of your landlord.  (Check other outlets for the same issue.)  Ask a real electrician if it's safe for now.

This is a big deal and you should have it fixed ASAP.

(The bigger slot is "hot", I think.)

The bigger slot is neutral

Order one of these and plug it into each outlet:

If it says REVERSE HOT GROUND call electrician immediately and unplug that receptacle immediately.

114 volts to 126 volts is OK, anything else, move!
