Slope of a velocity -time graph gives
A particle is moving in a circular path of radius $r$. The displacement after half a circle would be :
A cyclist travels a distance of $4\, km$ from $P$ to $Q$ and then moves a distance of $3\, km$ right angle to $PQ$. Find his resultant displacement graphically.
Write true or false for the following statements
A quantitv which can be represented completely by magnitude alone is called a vector quantity.
Can the displacement of a particle be zero when the distance travelled is not zero ?
