Question

In an atom 2 electrons move around the nucleus in circular orbits of radii r and 4 respectively the ratio of time taken by them to complete one revolution is

Answer 1

if r1 : r2 = r : 4 then T1 : T2 = r : 4 as T proportional to R...... becuz S = vt and T=(2*pie*R / v) as v is same for both T proportional to R
