Question

the kinetic energy of an in the second bohr’s orbit of a hydrogen atom is

Answer 1

So here I suppose if u are 10th or 12th class student follow these steps to get the ans on ur own calculations :—

1st write formulae of coulomb law ;charge=Ze &e

2nd write formulae of centripetal force =mv^2/r^2 : note here ^This sign is for power e.g. 2^2=4, 3^2=9

3rd now where this centripetal and coulomb FORCE work why they exist for This mathematically equal equation 1 and 2
