Assertion (A) When plane of coil is perpendicular to magnetic field, magnetic flux linked with the coil is minimum, but induced emf is zero.

Reason (R) $$\phi=n A B \cos \theta$$ and $$e=\frac{d \phi}{d t}$$

A 20 V AC is applied to a circuit consisting of a resistor and a coil with negligible resistance. If the voltage across the resistor is 12 V, the voltage across the coil is

The electric and the magnetic fields associated with an electromagnetic wave propagating along the $$z$$-axis, can be represented by

The graph between the maximum speed $$(v_{max})$$ of a photoelectron and frequency $$(\nu)$$ of the incident radiation, in photoelectric effect is correctly represented by
