Assume the graph of sepecific binding energy versus mass number is as shown in the figure. Using this graph, select the correct choice from the following.

Answer»

FUSION of two nuclei of mass number LYING in the RANGE of `100 lt A lt 200` will release energy
Fusion of two nuclei of mass number lying in the range of `51 lt A lt 100` will release energy
Fusion of two nuclei of mass number lying in the range of `1 lt A lt 50` will release energy.
Fission of the nuclous of mass number lying in the - range of `100 lt A lt 200` will release energy when broken into two fragments.

Solution :When two nuclei of mass number lying in the range of `51 lt A lt 100` combines, the a nucleus is formed in the range `100 lt A lt 150` which has high value of specific binding energy. Thus, the fusion of two nuclei of mass number lying in range of `51 lt A lt 100` will release energy.
