A bob is whirled in a horizontal plane by means of a string with an initial speed of $\omega \text{rpm}$. The tension in the string is $T$. If speed becomes $2\omega$ while keeping the same radius, the tension in the string becomes:

A particle moving with uniform speed in a circular path maintains:

A logic circuit provides the output $Y$ as per the following truth table: The expression for the output $Y$ is:

In the diagrams below, a strong bar magnet is moving towards solenoid-2 from solenoid-1 with velocity $v$. The magnet is oriented with its North pole (N) facing solenoid-2 and South pole (S) facing solenoid-1. The direction of induced current in solenoid-1 and that in solenoid-2, respectively, are through the directions:
