AIEEE 2009 PYQ Mock Test

This question contains Statement-1 and Statement-2. Of the four choices given after the statements,
choose the one that best describes the two statements.
Statement – 1: For a charged particle moving from point P to point Q, the net work done by an
electrostatic field on the particle is independent of the path connecting point P to point Q.
Statement-2: The net work done by a conservative force on an object moving along a closed loop is
zero

The above is a plot of binding energy per nucleon $E_b$, against the nuclear mass $M$; $A,B,C,D,E,F$ correspond to different nuclei. Consider four reactions:(i) $A+B\to C+\epsilon$ (ii) $C\to A+B+\epsilon$ (iii) $D+E\to F+\epsilon$ (iv) $F\to D+E+\epsilon$ where $\epsilon$ is the energy released. In which reactions is $\epsilon$ positive?

A p-n junction ($D$) shown in the figure can act as a rectifier. An alternating current source ($V$) is connected in the circuit.ShutterstockThe output voltage across the resistor is best represented by:

The logic circuit shown below has the input waveforms '$A$ ' and '$B$ ' as shown. Pick out the correct output waveform.

If $x$, $v$ and $a$ denote the displacement, the velocity and the acceleration of a particle executing simple harmonic motion of time period $T$, then, which of the following does not change with time?
