Various News Highlights: CDTI foundation stone laid, world's longest river cruise launched, Siyom Bridge inaugurated, Kollam becomes first constitution-literate district, and important results and formulas in physics.

• Amit Shah laid the foundation stone of the Central Detective Training Institute (CDTI) in Karnataka.
• The CDTI will be the sixth of its kind under the Bureau of Police Research and Development.
• PM Modi launched the world’s longest river cruise from Varanasi to Assam, covering over 3,200 km in 51 days.
• The luxury cruise will flow across 27 river systems in five states in India and Bangladesh.
• Rajnath Singh inaugurated the Siyom Bridge in Arunachal Pradesh, facilitating faster troop induction and heavy equipment transport to forward areas.
• The Siyom Bridge is a 100-metre steel arch superstructure on the Aalo-Yingkiong road.
• Kollam has become the first constitution-literate district in the country after a seven-month campaign.
• The physical quantities, symbols, dimensions, and units of vector area elements, electric field, electric flux, dipole moment, linear charge density, surface charge density, and volume charge density are important in physics.
• Frictional charges are charges developed on bodies when they are rubbed against each other.
• The charge on a body is expressed as q = ± ne, where n is an integer and e is the charge on an electron.
• Total positive or negative charge on an object of mass m having mass number A and atomic number Z is given as q = mNA × Z.
• Coulomb’s law states that the electrostatic force experienced by two charges q and q0 separated by a distance r is given by F = 1/4πε0 × qq0/r2.
