Question
A particle is constrained to move on a straight line path. It returns to the starting point after $10\, sec$. The total distance covered by the particle during this time is $30\, m$. Which of the following statements about the motion of the particle is false
✓

Answer

(c) Displacement of the particle will be zero because it comes back to its starting point

${\rm{Average\, speed }} = \frac{{{\rm{Total \,distance }}}}{{{\rm{Total\, time }}}} = \frac{{30m}}{{10\;sec}} = 3\;m/s$

A point source of light $S$ is placed at the bottom of a vessel containing a liquid of refractive index $5/3$. A person is viewing the source from above the surface. There is an opaque disc $D$ of radius $1\, cm$ floating on the surface of the liquid. The centre of the disc lies vertically above the source $S$. The liquid from the vessel is gradually drained out through a tap. The maximum height of the liquid for which the source cannot be seen at all from above is......$cm$
