Answer Key : (d) -

Assuming Zener diode does not undergo

Breakdown, current in circuit==8mA

∴voltage drop across diode=80 V50 V. The diode undergo breakdown.

Current is R1==14mA

Current is R2==5 mA

∴Current through diode=9mA



Next Question :

Four equal point charges Q each are placed in the xy placed at (0, 2), (4, 2), (4, −2) and (0, −2). The work required to put a fifth charge Q at the origin of the coordinate system will be:

(a)

(b)

 

(c)

(d)
