You are given a dipole of charge \( +q \) and \( -q \) separated by a distance \( 2l \). A sphere 'A' of radius \( R \) passes through the centre of the dipole as shown below and another sphere 'B' of radius \( 2R \) passes through the charge \( +q \). Then the electric flux through the sphere A is
Human bodies, like most animal bodies, are made up of four different types of tissue:
This tissue forms the outer layer of the body and also lines many of the body's cavities where it has a protective function.
General functions of epithelial tissue:-
This tissue assists in the support and protection of organs and limbs and depending on the location in the body it may join or separate organs or parts of the body.
This tissue enables various forms of movement, both voluntary and involuntary.
This tissue is responsible for the carrying of electrical and chemical signals and impulses from the brain and central nervous system to the periphery, and vice versa.
