• Chauhan Dynasty as per the chronological order:
  • Ajayraj - (1110 - 1135 AD).
  • Arnoraj - (1135 - 1150 AD).
  • Vigraharaj IV - (1150 - 1164 AD).
  • Prithviraj III - (1178 - 1192 AD).

Key Points

• According to the Raj Shekhar Prabandh Kosh, the Chauhan dynasty was established by Vasu Dev Chauhan in 551 AD.
  • Their initial capital was Ahichhitarpur.
  • After Vasudev Chauhan comes Samant Raj as his successor.
  • Durlabh raj was the first Chauhan emperor when the Muslims invaded Ajmer.

Additional Information 

• The Chauhan Dynasty:
  • The word Chauhan is the vernacular form of the Sanskrit term Chahamana.
  • While the earlier versions of Chandbardai's work Prithviraj Raso do not mention Chauhan as born from Agnikunda, the later versions do.
  • The 15th-century Hammira Mahakavya of Nayachandra Suri & Jayanayak's Prithviraj Vijay considers Chauhans as Suryavanshi. 
  • Based on Bijloia Inscription, Dr. Dasrath Sharma considers that the early ancestor of Chauhan was born at Ahichchhatrapura in the gotra of sage Vatsa. Ahichchhatrapura can be identified with modern Nagaur.
  • Chahamanas probably started out as petty rulers of Ahichchhatrapura. As the Chahamana territory expanded, the entire region ruled by them came to be known as Sapadalaksha.
• Major Chauhan dynasties include:
  • Chauhans of Shakambhari.
  • Chauhans of Ranthambore.
  • Chauhans of Jalore.

The correct answer is Software program.

• An operating system is system software that manages computer hardware, software resources, and provides common services for computer programs. Operating systems are found on many devices such as a computer, mobile phones, video games etc.
• Software program
  • It is a set of instructions, or a set of modules or procedures, through which computer operation is performed.
  • It is often called a software application and a software product.

Additional Information

• Computer system
  • A Computer system is usually defined as a combination of both hardware and software working together.
  • Hardware is the physical components of a computer and software is the programs that run on a computer.
• Network
  • It is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data.
  • E.g - The Internet, often referred to as the ‘Net’, consists of a complex network of computers connected by high-speed communication technologies like satellites, microwave devices, etc.
• Hardware device
  • Computer hardware includes the physical parts of a computer, such as a case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.
  • It accepts the data (input) from the user.
  • The computer has memory chips, which are designed to hold data until it is needed.
  • It processes this data into information. The computer has an electronic brain called the Central Processing Unit, which is responsible for processing all data into information according to the instructions given to the computer.
  • It then returns the processed information (output) to the user.

CONCEPT:

Force:

• The interaction which after applying on a body changes or try to changes the state of rest or state of motion is called force.
• It is denoted by F. The SI unit of force is Newton (N).

Force (F) = Mass (m) × acceleration (a)

• If more than one force is acting on a body, then the effect on the body is due to the net force.
• A stationary object on which no force is acting remains stationary.
• An object in motion continues to move with the same speed and direction when no force is acting on the object. This is Newton’s first law of motion. 

​CALCULATION:

Given:

Force = 20 N

Acceleration (a) = 2 m/s2

⇒ Force (F) = m a 

⇒ m = F/a = 20/2 = 10 kg.

So, option 4^th is correct.
