Questions Asked in NEET exam
- 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.

Concepts Used:
Ecosystem
An ecosystem is a structural and functional unit of ecology where the living organisms come in to interact with each other and the surrounding environment.
Structure of the Ecosystem:
The structure of an ecosystem is distinguished by the organization of both biotic and abiotic components. This involves the distribution of energy in our environment. It also comprises the climatic conditions prevailing in that particular environment.
There are two main components of the structure of an ecosystem, namely:
- Biotic Components
- Abiotic Components
The biotic and abiotic components are interconnected in an ecosystem. It is an open system where the energy and components can flow through the boundaries.
