MCQ
A shooting game involves using a gun that fires by itself at random times. The player can only point the gun in a fixed direction while the target moves from side to side with simple harmonic motion, as shown. At which of the given region should the player aim in order to score the greatest number of hits? 
  • A
    $3$
  • ✓
    either $1$ or $5$
  • C
    either $2$ or $4$
  • D
    any of $1, 2, 3,$ or $5$
✓

Answer

Correct option: B.
either $1$ or $5$
b
During $SHM$ speed will be minimum in $1$ and $5$ region.
Hence probability of greatest number of hit will increase.

In steady state heat conduction, the equations that determine the heat current $j ( r )$ [heat flowing per unit time per unit area] and temperature $T( r )$ in space are exactly the same as those governing the electric field $E ( r )$ and electrostatic potential $V( r )$ with the equivalence given in the table below.

$T( r )$ $V( r )$
$j ( r )$ $E ( r )$

We exploit this equivalence to predict the rate $Q$ of total heat flowing by conduction from the surfaces of spheres of varying radii, all maintained at the same temperature. If $\dot{Q} \propto R^{n}$, where $R$ is the radius, then the value of $n$ is
