Q. What happens to the induced EMF if the area of the coil is increased while the magnetic field strength remains constant?
A.
It increases
B.
It decreases
C.
It remains the same
D.
It becomes zero
Solution
Increasing the area of the coil while keeping the magnetic field strength constant increases the magnetic flux through the coil, which according to Faraday's law increases the induced EMF.
Q. What happens to the induced EMF if the rate of change of magnetic flux is doubled?
A.
It remains the same
B.
It doubles
C.
It halves
D.
It quadruples
Solution
According to Faraday's law, the induced EMF is directly proportional to the rate of change of magnetic flux. Therefore, if the rate is doubled, the induced EMF also doubles.
Q. What happens to the light ray when it hits the boundary at an angle greater than the critical angle?
A.
It is refracted
B.
It is absorbed
C.
It is reflected back into the denser medium
D.
It passes into the rarer medium
Solution
When the angle of incidence exceeds the critical angle, the light ray undergoes total internal reflection and is reflected back into the denser medium.
Correct Answer:
C
— It is reflected back into the denser medium
Q. What happens to the magnetic field inside a long solenoid when the current through it is increased?
A.
Magnetic field decreases
B.
Magnetic field remains constant
C.
Magnetic field increases
D.
Magnetic field becomes zero
Solution
The magnetic field inside a long solenoid is directly proportional to the current flowing through it. Increasing the current increases the magnetic field strength.
