Three girls skating on a circular ice ground of radius $200 \;m$ start from a point $P$ on the edge of the ground and reach a point $Q$ diametrically opposite to $P$ following different paths as shown in Figure. What is the magnitude of the displacement vector for each ? For which girl is this equal to the actual length of path skate ?
The angle between vector $\vec{Q}$ and the resultant of $(2 \overrightarrow{\mathrm{Q}}+2 \overrightarrow{\mathrm{P}})$ and $(2 \overrightarrow{\mathrm{Q}}-2 \overrightarrow{\mathrm{P}})$ is:
Give equation to find the value of resultant vector and the direction of two vectors.
If a particle moves from point $P (2,3,5)$ to point $Q (3,4,5)$. Its displacement vector be
A particle is simultaneously acted by two forces equal to $4\, N$ and $3 \,N$. The net force on the particle is
