Question: What happens when an electric dipole is placed in a non-uniform electric field?

Ans: When an electric dipole is placed in a non-uniform electric field, the dipole will have both rotational and translational motion. When the dipole becomes parallel to the electric field, the rotational motion will stop.

Question: An electric dipole consists of a positive and negative charge of 4µC each placed at a distance of 5mm.Calculate dipole moment.
Ans:
q = ±4µC = ±4 × 10-6C
p = q x 2a
2a = 5mm = 5 × 10-3 m
= 4 × 10-6 × 5 × 10-3
= 2 × 10-8 C- m

Electric Dipole: A system containing two equal and opposite charges separated by a finite distance is called an electric dipole.
Electric Dipole moment: Electric dipole moment is defined as the product of magnitude of one of the charges and length of the dipole say ‘2a’ i.e.
  • The electric dipole moment is a vector quantity.
  • It is directed from – q to + q i.e.from negative charge to the positive charge.
  • SI unit of electric dipole moment isCoulomb- meter (Cm).
  • The net charge on an electric dipole is zero.

Why is Hindi Day celebrated on 14 September?

Why is Hindi Day celebrated on 14 September? After independence, the Government of India set a goal to give an ideal form to the mother tongue of the country and set a target for grammar and orthography using the Devanagari script to bring standardization in writing. Subsequently, on September 14, 1949, the Constituent Assembly decided by a vote that Hindi would be the official language of India. To propagate the importance of this decision and to spread Hindi in every region, India is celebrating Hindi Day every year from 1953 to 14 September, at the request of Rashtrabhasha Prachar Samiti, Wardha. Apart from this, 14 September is also the birthday of Rajendra Singh, who worked tirelessly to make Hindi the official language of India. Hindi Day is observed every year on 14 September to mark the importance of the Hindi language in the country. The Hindi language is one of the oldest languages, which derives most of its academic vocabulary from the Sanskrit language written in the Deva

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material  Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne
