MCQ
In an elevator moving vertically up with an acceleration $'g\ ',$ the force exerted on the floor by a passenger of mass $M$ is:
  • A
    $Mg$
  • B
    $\frac{1}{2}\text{Mg}$
  • C
    zero
  • $2Mg$

Answer

Correct option: D.
$2Mg$
Force exerted by the passenger on floor
$= R = M(g + a)$
$= M(g + g)$
$= 2Mg$

An object is at a temperature of ${400^o}C$. At what temperature would it radiate energy twice as fast? The temperature of the surroundings may be assumed to be negligible
If two glass plates have water between them and are separated by very small distance (see figure), it is very difficult to pull them apart. It is because the water in between forms cylindrical surface on the side that gives rise to lower pressure in the water in comparison to atmosphere. If the radius of the cylindrical surface is $R$ and surface tension of water is $T$ then the pressure in water between the plates is lower by
