MCQ
A particle is moving along a straight line with increasing speed. Its angular momentum about a fixed point on this line
  • A
    Goes on increasing
  • B
    Goes on decreasing
  • C
    May be increasing or decreasing depending on direction of motion
  • Remains zero

Answer

Correct option: D.
Remains zero
d
$\mathrm{L}=0$ because angle between $\overrightarrow{\mathrm{r}} \& \overrightarrow{\mathrm{v}}$ is always

zero (as point lies on the same line)

Mass of the pulley is $m$ & radius is $R$. Assume pulley to be uniform disc. Pulley is free to rotate about an axis passing through its centre and perpendicular to its plane. String is massless & inextensible. String is wrapped on the pulley. There is no slipping between string and pulley. The length of the string which is not wrapped on the pulley is $2R$. Block of mass $m$ is released from the position as shown in the figure. The impulse exerted by the string on the pulley at the moment string becomes taut is $J. \frac{2m \sqrt{gR}}{J}$ is equal to.
In the figure shown, a liquid is flowing through a tube at the rate of $0.1\, m^3/sec$. The tube is branched into two semicircular tubes of cross-sectional area $A/3$ and $2A/3$. The velocity of liquid at $Q$ is ......... $ m/sec$ (The cross-section of the main tube $= A =10^{-2}\, m^2$ and $v_p = 20\, m/sec$)

A concave mirror of radius of curvature $R$ has a circular outline of radius $r$. A circular disc is to be placed normal to the axis at the focus, so that it collects all the light that is reflected from the mirror from a beam parallel to the axis. For $r \ll R$, the area of this disc has to be at least
A metal surface is illuminated by light of two different wavelengths $248 \ nm$ and $310 \ nm$. The maximum speeds of the photoelectrons corresponding to these wavelengths are $u_1$ and $u_2$, respectively.
