Q1: If two point charges, each of ‘q’ are separated by a distance ‘2a,’  then what will be the electric potential at their midpoint?

Options:

1. \[\frac{q}{2 \pi \epsilon _{0} a}\]

2. Zero

3. \[\frac{q}{8 \pi \epsilon _{0} A}\]

4. \[\frac{q}{2 \pi \epsilon _{0} a^{2}}\]

Objective Answer: (a)

Explanation: We know that electric potential, V = \[\frac{q}{4 \pi \epsilon _{0} d}\]

VMIDPOINT  = \[\frac{q}{4 \pi \epsilon _{0} a}\] + \[\frac{q}{4 \pi \epsilon _{0} a}\] (As d = a)

=> VMIDPOINT  = \[\frac{q}{2 \pi \epsilon _{0} a}\]

Q2: State Biot-Savart’s law. Define the unit of Current.

Answer: Biot-Savart’s law is used to determine magnetic field intensity ‘H’ produced by the steady electric current in an infinitely long straight wire. This law relates the magnetic field to the following attributes of the electric current:

• Magnitude

• Direction

• Length, and

• The proximity of the current.

The unit of current is Ampere. Ampere is the flow of charge across the surface at the rate of 1 C/s.

Q1: Explain OR and AND Gate in terms of the following: 

(i) Boolean expression 

(ii) Truth Table

Answer: 

(i) OR Gate

Boolean Expression: A + B

Truth Table

(ii) AND Gate

Boolean expression: A . B

Truth Table

Q2: State Two Laws of the Photoelectric Effect.

Answer: 

First Law: Photoelectric current is directly proportional to the intensity of incident light, provided that the radiation’s frequency is greater than the threshold frequency.

Second Law: Photoelectric emission is an instantaneous emission process. This means there is no lag between the incident of light and the emission of electrons from the surface.

Q1: If monochromatic light of frequency 6 x 1014Hzis produced by a laser, then what will the energy of a photon in the beam light?

Solution: 

Given f = 6 x 1014Hz

We know that E = hf, and h = Planck’s constant = 6.6 x 10-34Js

So, E = 6.6 x 10-34 x 6 x 1014= 3.96 x 10-19J

Q2: What does a depletion layer of the P-N junction diode contain?

Options:

1. Electrons

2. Immobile ions

3. Mobile ions

4. Protons

Objective Answer: (b)
