In the circuit shown in figure the maximum output voltage V0 is

|
(a) 0 V |
(b) 5 V |
(c) 10 V |
(d) |
Assertion : If a point charge q is placed in front of an infinite grounded conducting plane surface, the point charge will experience a force.
Reason : This force is due to the induced charge on the conducting surface which is at zero potential.
|
(a) If both assertion and reason are true and the reason is the correct explanation of the assertion. |
|
(b) If both assertion and reason are true but reason is not the correct explanation of the assertion. |
|
(c) If assertion is true but reason is false. |
|
(d) If the assertion and reason both are false. |
Assertion : The back emf in a dc motor is maximum when the motor has just been switched on.
Reason : When motor is switched on it has maximum speed.
|
(a) If both assertion and reason are true and the reason is the correct explanation of the assertion. |
|
(b) If both assertion and reason are true but reason is not the correct explanation of the assertion. |
|
(c) If assertion is true but reason is false. |
|
(d) If the assertion and reason both are false. |
