Can the resultant of $2$ vectors be zero
Yes, when the $2$ vectors are same in magnitude and direction
No
Yes, when the $2$ vectors are same in magnitude but opposite in sense
Yes, when the $2$ vectors are same in magnitude making an angle of $\frac{{2\pi }}{3}$ with each other
The five sides of a regular pentagon are represented by vectors $A _1, A _2, A _3, A _4$ and $A _5$, in cyclic order as shown below. Corresponding vertices are represented by $B _1, B _2, B _3, B _4$ and $B _5$, drawn from the centre of the pentagon.Then, $B _2+ B _3+ B _4+ B _5$ is equal to
Figure shows a body of mass m moving with a uniform speed $v$ along a circle of radius $r$. The change in velocity in going from $A$ to $B$ is
The maximum and minimum magnitude of the resultant of two given vectors are $17 $ units and $7$ unit respectively. If these two vectors are at right angles to each other, the magnitude of their resultant is
Give equation to find the value of resultant vector and the direction of two vectors.
Two forces with equal magnitudes $F$ act on a body and the magnitude of the resultant force is $F/3$. The angle between the two forces is
