Class 12th

The ability to do work on a charge is called the electric potential and the ability to store charge is termed as the capacitance.

The movement of the body in the conductor is caused by the magnetic field. This magnetic field then causes an electric current to flow in the system. Hence, the direct action is caused by the magnetic force on the object, due to which it becomes the major source of motional EMF.

For a region of constant electric potential

(1) The electric field may be uniform

(2) The electric field may be zero

(3) There can be no charge inside the region

${}_Z{}^{A}X+{}_1{}^{1}H\to {}_2{}^{4}He+{}_8{}^{16}O$

$Z+1=2+8?Z=9X\to F$

$A+1=4+16\Rightarrow A=19$

$\Rightarrow {}_Z{}^{A}X={}_9{}^{19}F$

${}_7{}^{14}N+{}_Z{}^{A}Y\to {}_1{}^{1}H+{}_6{}^{14}C$

$7+Z=1+6?Z=0$

$14+A=1+14?A=1$

$?{}_Z{}^{A}Y={}_0{}^{1}n$

The spectrum of H-atom is formulated and drawn by Bohr's model. These spectrums are line spectrum. Lyman series lies in UV region, Balmer Partly lies UV and partly in the visible region and Paschen series lies in the infrared region.
