266293 The number of turns of primary and secondary coils of a transformer are 5 and 10 respectively and the mutual inductance of the transformer is 25 henry. Now the number of turns in the primary and secondary of the transformer are made 10 and 5 respectively. The mutual inductance of the transformer in henry will be:

1 6.25
2 12.5
3 25
4 50

266294 Statement I: The Q value of a nuclear process given by \(\mathrm{Q}=\) final kinetic energy - initial kinetic energy Statement II: The Q value of nuclear process is \(Q=\) (sum of final masses - sum of initial masses) \(\times \mathrm{C}^2\)

1 Statement I is correct and Statement II is incorrect
2 Statement I is incorrect and Statemnet II is correct

266295 When unpolarised light beam is incident from air into glass ( \(\mathrm{n}=\mathbf{1 . 5}\) ) at the polarising angle:

1 Reflected beam is polarised 100 percent
2 Reflected and refracted beams are partially polarised
3 The reason for (a.) is that almost all the light is reflected
4 All of the above
TEST SERIES (PHYSICS FST)

266296 Statement I: The binding energy per nucleon, \(\mathrm{E}_{\mathrm{in}}\), is practically constant, i.e. practically independent of the atomic number for nuclei of middle mass number ( \(30<\mathrm{A}<170\) ). The curve has a maximum of about 8.75 MeV for \(\mathrm{A}=56\) and has a value of 7.6 MeV for \(\mathrm{A}=238\). Statement II : \(\mathrm{E}_{\mathrm{tn}}\) is lower for both light nuclei ( \(A<30\) ) and heavy nuclei ( \(A>170\) ) in comparison to \(\mathrm{E}_{\mathrm{m}}\) of nuclei of intermediate atomic number.
