circumstances of 1st orbit = 2π × radius of 1st orbit = 3.332 × 10^-10 m

2 × 22/7 × radius of 1st orbit = 3.332 × 10^-10 m

radius of 1st orbit = (3.332/6.28 ) × 10^-10

= (0.529) × 10^-10

now, use ,

mvr = nh/2π { according to Bohr theory

v = h/2πmr { n = 1 ( 1st orbit

put value of h= 6.626 × 10^-34 , m = 9.1 × 10^-31 kg ,r = 0.529 × 10^-10

v = 2.188× 10^6 m/s
≈ 2.19 × 10^6 m/s (approximately)

anil43: its 2nd orbit of hydrogen atom
anil43: okay okay i understand thx for your kind help
