Actually Welcome to the Concept of the Operational Amplifiers

Now basically here we are dealing with an OPAMP

for which the Voltage gain is given as,

Acl = -Rf/Ri

and The Output Voltage is given as

⭐Vout = Acl * Vin

thus we get here as

When we use the formula

Acl (Gain) = - 200 k ohm / 2 k ohm

⭐Acl ( Gain) = - 100

thus from this we get as

Vout = -100 * 2.5

Vout = -250 MV

thus we get as,

⭐Vout = 0.25 V
