- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
In the light of the above statements, choose the correct answer from the options given below :- NEET (UG) - 2024
- Magnetic Field

Growth in Plants:
Plants have the distinctive ability to grow throughout their life. The meristem cells present there in the roots and shoot apical lead to the primary growth of the plant. The primary growth which happens or takes place at the tips of the stem and roots of the plant contributes to the elongation of the plant along its axis.
In the later stages of growth in plants, the growth in dicotyledonous, vascular cambium, gymnosperms, and cork-cambium are also caused by the existence of meristems in them. These intercalary meristems are put up to increase the girth of the organs of the plant in which they are active. Such type of growth is commonly known as secondary growth.
Many parameters such as area, volume, fresh weight, cell number, dry weight, length, etc are utilized to measure the growth in plants as increase in the amount of protoplasm is responsible for the growth in plants.
