from a point p on the surface of radius 3 cm two cockroaches a and b started moving along two different circular paths each having the maximum possible radius on the surface of the sphere that lie in the two different planes which are inclined at an angle of 45 degrees to each other. if a and b take 18 sec and 6 sec respectively to complete one revolution along with their respective circular paths then after how much time will they meet again after they start from p?

Time taken for them to meet sqrt[T(1)*T(2)] S(1)/S(2) = sqrt[T(2)/T(1)] Two bodies begin from inverse finishes P and Q in the meantime and move towards each other with speeds S(1) and S(2).
They achieve the contrary finishes and turn around headings. {S(1)>S(2) and S(1) Total separation secured till nth gathering (2n-1)D and time taken (2n-1)D/S(1)+S(2).
