Binding energy of deuterium is 2 23 Mev then its mass defect in a m u is 1 0 0024 3 0 0012 2 0 0012 4 0 0024

For a first order reaction the time taken to reduce 1 the initial concentration to a factor of is 10 minute 4 If the reduction in concentration is carried out to a factor of then time required will be 1 16 1 10 minutes 2 20 minutes

Binding Energy per nucleon of a fixed nucleus X is 6 MeV It absorbs a neutron moving with KE 2 MeV and converts into Y at ground state emitting a photon of energy 1 MeV The Binding Energy per nucleon of Y in Me is O 64 1 A 1 C O 64 1 4 1 O T

3 In the pair production process a y ray photon creates an electron positron pair If the total kinetic energy of electron and positron is 0 78 MeV then the energy of y ray photon is 1 1 80 MeV 2 1 10 MeV 3 1 01 MeV 4 1 27 MeV

During fusion reaction the device in which magnetic field is used to confine the plasma is called 1 Breeder reactor 2 Moderator 3 Tokamak 4 Geiger Nuttal counter

61 If mass of electron is equal to 1840 mass of proton then energy of y photon required for the pair production of an electron and positron is 1 Less than 1 01 MeV 2 Equal to 1 01 MeV 3 Greater than 1 01 MeV times the Less than or equal to 1 01 MeV E
