Rajasthan Board Class 12 Physics Question Paper and Solution 2016

By | March 1, 2019

Solving earlier years’ board query papers is an ideal follow to analyse your susceptible and robust spaces so you can amend your arrangements accordingly. It can even can help you to understand in regards to the essential subjects which can be time and again asking in board assessments. Students will have to have an concept in regards to the development and problem degree of the query paper earlier than writing board assessments. For this, scholars can remedy earlier years’ query papers. It won’t simplest assist scholars to get accustomed to the trouble degree but additionally assist them to understand the right kind technique to write resolution within the upcoming board assessments.  In this text, we’re offering the Rajasthan Board Class 12 Physics Solved Question Paper 2016 within the PDF shape.

Question:

A rate q enters perpendicularly with the route of a magnetic box  with a pace . What will be the pressure performing in this rate?

Solution:

The pressure is given through F = qvBsinθ the place θ is the attitude between the magnetic box and the particle pace.

Now, it’s for the reason that the rate q enters perpendicularly with the route of a magnetic box.

Therefore, θ = 90

Therefore, the pressure performing at the rate q is qvB.

Question:

Write the Faraday’s regulation of electromagnetic induction.

Solution:

According to Faraday’s regulation of electromagnetic induction “the magnitude of the brought on emf in a circuit is the same as the time charge of alternate of magnetic flux throughout the circuit.

Question:

What is farsightedness or hypermetropia?

Solution:

The farsightedness (hyperopia) is a not unusual imaginative and prescient situation during which you’ll see far away items obviously, however items within sight could also be blurry. The level of your farsightedness influences your focusing talent.

Question:

Write the 2 examples of acceptor impurities.

Solution:

An acceptor impurity accepts an electron from an adjoining atom to create a hollow. They are sometimes called p-type impurities. The examples of acceptor impurities are boron, gallium, and indium.

Question:

Write the SI unit of present denisity.

Solution:

The SI unit of the present density is amperes consistent with sq. metre (amp/m2).

Question:

Write two traits of a subject material to constructs an everlasting magnet. Give two examples of such fabrics.

Solution:

The two traits of a subject material to constructs an everlasting magnet are:

  • The subject material will have to have top retentivity in order that the magnet is robust and top coercivity in order that the magnetisation isn’t erased through stray magnetic fields, temperature fluctuations or minor mechanical harm.
  • The subject material will have to have a top permeability.

Examples of such fabrics are metal, alnico, cobalt metal and ticonal.

Question:

What is preventing voltage (or minimize voltage)? Plot a graph of variation of photoelectric present with collector plate attainable for 2 incident radiations of identical frequency and other intensities.

Solution:

For a specific frequency of incident radiation, the minimal detrimental (retarding) attainable V given to the plate A for which the photocurrent stops or turns into 0 is named the cut-off or preventing attainable.

The graph of variation of photoelectric present with collector plate attainable for 2 incident radiations of identical frequency and other intensities is given under:

Question:

Write definitions

(i) Transducer

(ii) Modulation

Solution:

(i) Transducer: Any tool that converts one type of power into some other can also be termed as a transducer. An electric transducer could also be outlined as a tool that converts some bodily variable (force, displacement, pressure, temperature, and many others) into corresponding diversifications within the electric sign at its output.

(ii) Modulation: The authentic low frequency message/data sign can’t be transmitted to lengthy distances. Therefore, on the transmitter, data contained within the low frequency message sign is superimposed on a top frequency wave, which acts as a service of the tips. This procedure is referred to as modulation. There are various kinds of modulation like Amplitude Modulation (AM), Frequency Modulation (FM) and Phase Modulation (PM).
