Question Discussion & Solution

Key Points

Thus, the correct match is A (III), B (II), C (IV), D (I)

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.

Total number of sarees = 40

Code number written on the 16^th saree = 85091

Code number written on the 29^th saree = 85091 + (29 – 16) = 85091 + 13 = 85104

The correct answer is First.

• In the year 2017-18, Rajasthan was the largest millet producing state of India.

Key Points

• Rajasthan was followed by Maharashtra and Karnataka.
• The year 2023 will be observed as the International Year of Millets. 
• The Central Government declared 2018 as the year of millets. 
• Millet Mission comes under the National Food Security Mission (NFSM) which was launched in October 2007. 
• Millets include Jowar and ragi etc.

Additional Information 

• Types of Crops in India:
  • Kharif: Sown in June/July, harvested in September/October, e.g., rice, jowar, bajra, ragi, maize, cotton, and jute.
  • Rabi: Sown in October/December, harvested in April/May, e.g., wheat, barley, peas, rapeseed, mustard grains.
  • Zyad: They are raised between April/June, e.g., melons, watermelons, cucumbers, toor, leafy and other vegetables.
