A radioactive isotope has a decay constant of 10-5s4. Calculate half life
-
A.
6.93 x 105s -
B.
6.93 x 105s -
C.
6.93 x104s -
D.
6.93 x 104s
Correct Answer: Option C
Explanation
T (1)/2 = (0.693)/λ = (0.693)/10-5
= 0.693 x 105
= 6.93 x 104 sec
T (1)/2 = (0.693)/λ = (0.693)/10-5
= 0.693 x 105
= 6.93 x 104 sec
