Question
When a magnet is pushed in and out of a circular coil C connected to a very sensitive galvanometer G as shown in the adjoining diagram with a frequency 
, then
- Constant deflection is observed in the galvanometer
- Visible small oscillations will be observed in the galvanometer if is about 50 Hz
- Oscillations in the deflection will be observed clearly if
or 2 Hz
- No variation in the deflection will be seen if or 2 Hz
is about 50 Hz
or 2 Hz
or 2 Hz
The correct answer is: Oscillations in the deflection will be observed clearly if or 2 Hz
When frequency is high, the galvanometer will not show deflection.
