Question 1
4 / -1

Assertion An aircraft flies along the meridian, the potential at the ends of its wings will be the same.
Reason Whenever there is change in the magnetic flux e.m.f. induces.

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.

E
If Assertion is false but Reason is true.
Question 2
4 / -1

Assertion A spark occurs between the poles of a switch when the switch is opened.
Reason Current flowing in the conductor produces magnetic field.

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.

E
If Assertion is false but Reason is true.
Question 3
4 / -1

Assertion In the phenomenon of mutual induction, self-induction of each of the coils persists.

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.

E
If Assertion is false but Reason is true.
Question 4
4 / -1

Assertion Lenz\'s law violates the principle of conservation of energy.
Reason Induced e.m.f. always opposes the change in magnetic flux responsible for its production.

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.

E
If Assertion is false but Reason is true.
Question 5
4 / -1

Assertion The back e.m.f. 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.

E
If Assertion is false but Reason is true.

Solution
Question 6
4 / -1

Assertion An induced e.m.f. is generated when magnet is withdrawn from the solenoid.
Reason The relative motion between magnet and solenoid induces e.m.f.

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.

E
If Assertion is false but Reason is true.
Question 7
4 / -1

Assertion An artificial satellite with a metal surface is moving above the earth in a circular orbit. A current will be induced in satellite if the plane of the orbit is inclined to the plane of the equator.
Reason The current will be induced only when the speed of satellite is more than 8 km/sec.

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.

E
If Assertion is false but Reason is true.
Question 8
4 / -1

Assertion An electric motor will have maximum efficiency when back e.m.f. is equal to applied e.m.f.
Reason Efficiency of electric motor is depends only on magnitude of back e.m.f.
