Question Discussion & Solution

The correct answer is option 4) i.e. ∞

CONCEPT:

• ​The time period of a pendulum is given by the equation:

​\(\Rightarrow T = 2\pi\sqrt{\frac {L}{g}}\)

Where L is the length of the string of pendulum and g is the acceleration due to gravity.

EXPLANATION:

• At a height of 900 km from the earth's surface gravity is absent.

Therefore, g = 0.

Substituting g = 0,

\(\Rightarrow T = 2\pi\sqrt{\frac {L}{0}} = ∞\)

Thus, the time period of the pendulum at a distance of 900 km from the Earth will be infinite.

The correct answer is 1921.

• The Begun Kisan Andolan was started in 1921.

Key Points

• Begun Kisan Andolan:
  • It was one of the farmer's movements of Rajasthan during British Raj in India.
  • It was started in Menal village in 1921.
  • Begun is a village in Chittorgarh district.
  • Vijay Singh Pathik was the leader of this movement to Ramnarayan Chaudhary.
  • In 2023, an agreement was made between Rajasthan Sewa Sangh and Rawat Sawai Anup Singh Ji to settle the dispute but it was opposed by the government naming it a Bolshevik agreement and the government appointed a government employee in the place of Thikanedar under its Munsarmat policy. 
  • The leadership of this movement was later handed over to Vijay Singh Pathik. 

The correct answer is SRAM.

​Key Points

• SRAM memory devices are very much similar, mainly in terms of speed, to the cache memory.
• SRAM stands for Static random-access memory.
• Static random-access memory is a type of random-access memory that uses latching circuitry to store each bit.
• SRAM is volatile memory; data is lost when power is removed.
• The term static differentiates SRAM from DRAM which must be periodically refreshed.

Additional Information

• Dynamic random access memory (DRAM) is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.
• Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level.
• EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage.

The correct answer is Social Justice and Empowerment.

• As of June 2020, Master Bhanwarlal Meghwal is the Cabinet Minister of Social Justice and Empowerment in Rajasthan.

Key Points

• Bhanwarlal Meghwal is a politician belonging to the Indian National Congress.
• His constituency is Sujangarh Churu, Rajasthan.
• He has served as Cabinet Minister of Social Justice and Empowerment in Rajasthan State Government.
• He also served as the Education Minister.

Additional Information

• Ministry of Social Justice and Empowerment:
  • It is responsible for welfare, social justice, and empowerment of marginalized sections of society like SCs, STs, and LGBTQ, etc.
  • At the centre, Thaawar Chand Gehlot is the Minister of Social Justice and Empowerment.
• Rajasthan:
  • Lok Sabha seat: 25
  • Number of Constituencies: 200

The pattern followed here is:

25 → First digit of 23 and second digit of 65.

68 → First digit of 61 and second digit of 38.

? → First digit of 72 and second digit of 48 → 78.

Hence, the answer is 78.
