a+ar_(1)+ar_(1)^(2)+...+oo and a+ar_(2)+ar_(2)^(2)+...+oo be two infinite series of positive numbers with the same first term.The sum of the first series is r_(1) and the sum of the second series r_(2). Then the value of (r_(1)+r_(2)) is

For balmer series wavelength of first line is lambda_(1) and for brackett series wavelength of first line is lambda_(2) then (lambda_(1))/(lambda_(2)) is

A number N is divided into three parts such that sum of first 2 parts is equal to K% of 3rd part. What is the 3rd part?

For Balmer series , wavelength of first line is 1 lambda and for Brackett series, wavelength of first line is 2lambda then their ratio is

Assertion: In any transition series the magnetic moment of M^(2+) ions first decreases Reason: In a transition series, the number of unpaired electrons first increases and then decreases.

A long resistance wire is divided into 2n parts. Then n parts are connected in series and the other n parts in parallel separately. Both combinations are connected to identical supplies. Then the ratio of heat produced in series to parallel combinations will be -
