00:02The question is, according to Bohr's theory, the moment of momentum of an electron revolving
00:13in second orbit of hydrogen atom will be a 2 pi h, b pi h, c h upon pi, d
00:252 h upon pi.
00:30Here it is asking about moment of momentum means angular momentum.
00:37So according to Bohr's angular momentum of electron is calculated by the formula L is
00:42equal to n h upon 2 pi, here the value of n is 2, so L will be equal to
00:552 into h upon
00:582 pi, so 2 will be get cancelled with 2, so L will be equal to h upon pi, so
01:10the correct
01:10option will be c h upon pi.
