These flashcards cover key concepts from the CUET Physics exam paper, focusing on topics such as electric fields, electromagnetic waves, current flow, and potential energy.

What is the angle of deviation for a ray incident normally on the face of an equilateral prism?

The angle of deviation is 60°.

What happens to the path of charge moving parallel to a uniform magnetic field?

It travels in a straight line.

As the wavelength of incident light on a photocell changes, how does the plate current vary?

The plate current varies with the wavelength.

Arrange the following EM waves in increasing order of frequency: Radio Waves, Infrared waves, Ultraviolet Rays, X-Rays, Gamma Rays.

Radio Waves < Infrared waves < Ultraviolet Rays < X-Rays < Gamma Rays.

What is the electric field due to a thin spherical shell?

The electric field outside a uniformly charged thin spherical shell is zero.

For an infinitively long straight conductor, what is the magnetic field at a distance r?

B = (μ₀I)/(2πr).

If the current is flowing in two AC circuits, one containing a pure inductor and the other a capacitor, what happens if the frequency increases?

The current will decrease in the inductor circuit and increase in the capacitor circuit.

E = 3.1 eV.

When two identical circular wires carry current, how do you find the net magnetic field at their common center?

Add the magnetic fields due to each wire vectorially at the common center.

What is the mutual inductance between two coils if their effective flux is completely linked?

M = L1 = L2.

For a Dielectric slab of thickness d, what happens to the electric field when it is introduced in a capacitor?

The capacitance of the capacitor increases.

-2.75 eV in the ground state.

What is the work done when an electric dipole is rotated in an electric field?

W = -pEcos(θ).

What current flows through a 1Ω resistor when connected to a 20V battery?

20A.

What happens to a charged particle in a uniform electric field?

It experiences a non-uniform force.

If the radius of the first orbit in a hydrogen atom is r, what is the radius of the third orbit?

The radius of the third orbit is 9r.

What is the stopping potential in photoelectric effect?

It is independent of the intensity of the radiation.

In the photoelectric effect, how does the maximum kinetic energy change with the frequency of the incident light?

It increases with frequency.
