The counting rate observed from a radioactive source at t=0 second was 1600 counts per second and t =8 seconds it was 100 counts per second. The counting rate observed as counts per second t = 6 seconds will be

The counting rate observed from a radioactive source at t = 0 seconds was 1600 counts per second and t = 8 seconds it was 100 count per second. The counting rate observed, as counts per second at t = 6 seconds will be :

The counting rate observed from a radioactive source at t=0 second was 1600 counts per second and at t=8 seconds it was 100 counts per second. The counting rate observed, as counts per second at t=6 seconds, willbe

The initial count rate for a radioactive source was found to be 1600 count/sec.and t = 8 sec this rate was 100 count/sec. What was the count rate at t = 6 [in counts/sec]-
