​

Answer 1

expression for speed of orbit in nth orbit is

V=e²/2eóhn

i.e.v = inversely proportional to 1/n

Answer 2

Answer:

Given: the ratio velocity of an electron in the nth orbit to the velocity of light (v) is 1:411. ≈3 (since n cannot be a decimal number). So, the correct answer is Option D. where n is the number of orbits, h is the Planck's constant, m is the mass of an electron, r is the radius of the orbit.

Heyyyy.... How r uhh???..xD
