A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :

Haloalkanes and Haloarenes - Nomenclature
Nomenclature of Haloalkanes:
‘Alkyl halide’ is the very common name for haloalkanes. The written format for haloalkane in the IUPAC name is “numerical position-alphabetically placed halo- root-word-ane”
Nomenclature of Haloarenes:
‘Aryl Halide’ is the very common name for haloarenes. In the nomenclature system, the numerical prefixes are named, depending on the basic position of the halogen atom in the aromatic ring.
In presence of more than one halogen atom, the halogen group is named and the aromatic ring is numbered based on the numerical position of the aromatic ring. Numerical prefixes are written in the format (1, 2) ; (1,3) ; (1,4). Always the least number is given to the halogen number.
