Which of the following is correct statement?
(A) The ratio of e/m value for H^+ & He^+ is 1: 2.
(B) The ratio of e/m value for He^+ & Li^2+ is 7: 8.
(C) The ratio of e/m value for Li^2+ & Be^3+ is 9: 8.
(D) The ratio of e/m value for [IMAGE] &
[IMAGE] is 1: 2.
?
Show answer and solution
Ratio of e/m value for H^+ & He^+ = 4: 1
Ratio of e/m value for He^+ & Li^2+ = 7: 8
Ratio of e/m value for Li^2+ & Be^3+= 16: 21
Ratio of e/m value for [IMAGE] & [IMAGE] = 2: 1
H^+ He^+ e/m = 4: 1
He^+ Li^2+ e/m = 7: 8
Li^2+ Be^3+ e/m = 16: 21
= 2: 1
Ratio of e/m value for He^+ & Li^2+ = 7: 8
Ratio of e/m value for Li^2+ & Be^3+= 16: 21
Ratio of e/m value for [IMAGE] & [IMAGE] = 2: 1
H^+ He^+ e/m = 4: 1
He^+ Li^2+ e/m = 7: 8
Li^2+ Be^3+ e/m = 16: 21
= 2: 1
