When the deflecting torque equals the controlling torque in an analogue instrument, the pointer will

1. rise to give the required reading

4. oscillate around the required reading

The answer is :- 3 When the controlling torque is equal (and opposite) to the deflecting torque a steady deflection will be obtained.
