Question Discussion & Solution

An animal walked 29 m south.

From here it turned right and walked 14 m.

Now it again turned right and walked 18 m.

Now it turned left and walked 27 m.

Animal facing West now.

Hence, option 2 is the correct answer.

According to the question, we have the following diagram,

Hence, Kritika is standing in the south-west direction with respect to her initial position.

The correct answer is 240 J.

Key Points

• When a force is applied to an object which causes displacement along the direction of force then the work is said to be done by that force.
• The work done by a force is defined as "the product of the component of the applied force on the block in the direction of the displacement and the magnitude of this displacement" is called work done.

Additional Information

• i.e., \(W = \vec F.d\vec x = Fdx\cos \theta \)

or in terms of magnitude, it can be given as

\(W\; = \;F \times s\)

• Here both force and displacement will be along the same direction since force is causing this displacement thus Work done is a scalar quantity.
  • Here,
  • Force applied on object = F
  • Displacement of object = dx
  • Distance traveled by an object = s
  • The angle between Force and displacement = θ
• Calculation:
  • Given that,
  • Person raised the box of weight 120 N through the height of 2 m
  • i.e., F = 120 N 
  • x = 2 m
• Thus from the above explanation, we can see that
• Work = Force × Distance moved in the direction of the force
• Force of 120 N is acting downwards, Therefore
  • Work Done = 120 × 2 = 240 J

The correct answer is ​Uttar Pradesh.

• Uttar Pradesh is the highest milk-producing state of India.

Key Points

• It produces around 18% of the country's total milk production.
• It is followed by Rajasthan which produces 11%, Andhra Pradesh producing 10%, Gujarat at 8% and Punjab produces 7%.
• India produces around 146 million MT of milk and is the largest producer of milk worldwide.
• Indian Dairy market is considered to be the largest and fastest-growing market in the world.
• India also exports around 0.2 billion USD which includes products like skimmed milk powder korma cream etc.
• The major countries are UAE, Bangladesh and other Southeast Asian countries.

The correct answer is Zila Parishad → Panchayat Samiti → Village Panchayat.

Key Points

• Panchayati Raj
  • Panchayati Raj is the system of local self-government of villages in rural India as opposed to urban and suburban municipalities.
  • It consists of the Panchayati Raj Institutions (PRIs) through which the self-government of villages is realized.
  • They are tasked with "economic development, strengthening social justice and implementation of Central and State Government Schemes including those 29 subjects listed in the Eleventh Schedule."
  • ​Part IX of the Indian Constitution is the section of the Constitution relating to the Panchayats.
  • It stipulates that in states or Union Territories with more than two million inhabitants there are three levels of PRIs:
    • Zilla Parishad at the District Level
    • Panchayat Samiti at the Block Level
    • Gram/Village Panchayat at the Village Level

 Additional Information

• The Panchayat Raj system was first adopted by the state of Rajasthan in Nagaur district on 2 Oct 1959 but first started by Andhra Pradesh.
• During the 1950s and 60s, other state governments adopted this system as laws were passed to establish panchayats in various states.
• The modern Panchayati Raj system was introduced in India by the 73rd constitutional amendment in 1993.
