The half life period of a radioactive substance is best determined by counting the number of alpha particles emitted per second in a Geiger Muller counter from its known quantity. If the half life period of a radioactive substance is one month, then

L/8th of it will remain intact at the end of four months

It will completely disintegrate in two months

3/4th of it will disintegrate in two months

It will completely disintegrate in four months

TRUE ANSWER : ?
YOUR ANSWER : ?

An electron has a mass that is approximately __________ that of the proton.

1

∞

1/1836 (approximately)

1836 (approximately)

TRUE ANSWER : ?
YOUR ANSWER : ?

Fission of U-235 on slow neutron bombardment can be represented by

92U235 + 0n1 → 56Ba143 + 36Kr90 + 3 0n1

92U235 + 0n1 → 56Ba143 + 36Kr90

92U235 + 0n1 → 56Ba143 + 36Kr90 + 3 0n1 + Q (energy)

92U235 + 0n1 → 92U236 + 3 0n1+ Q (energy)
