Q. What is the critical angle for a medium with a refractive index of 1.5? (2019)
A.
30 degrees
B.
45 degrees
C.
60 degrees
D.
90 degrees
Solution
The critical angle θc can be calculated using sin(θc) = 1/n. Thus, θc = sin^(-1)(1/1.5) = sin^(-1)(0.6667) ≈ 41.81 degrees, which is closest to 60 degrees.
Q. What is the direction of the magnetic field due to a current flowing in a circular loop when viewed from above? (2023)
A.
Out of the plane
B.
Into the plane
C.
Clockwise
D.
Counterclockwise
Solution
Using the right-hand rule, if the current flows in a counterclockwise direction when viewed from above, the magnetic field direction is out of the plane.
Q. What is the effect of dielectric on the capacitance of a capacitor? (2021)
A.
Increases capacitance
B.
Decreases capacitance
C.
No effect
D.
Depends on the voltage
Solution
Introducing a dielectric material between the plates of a capacitor increases its capacitance by a factor equal to the dielectric constant (κ) of the material.
