Two forces of 6 N and 8 N act at a point at right angles to each other. What is the magnitude of their resultant force?

The forces are such that the sum of their magnitude is 18 N and their resultant is perpendicular to the smaller force and magnitude of resultant is 12 N. Then the magnitudes of the forces are

If two vectors of equal magnitude act at an angle of 120 degrees to each other, what is the magnitude of their resultant vector?

Three coplanar forces $\vec{F_1}$, $\vec{F_2}$, and $\vec{F_3}$ act on a point object such that the object is in equilibrium. If $|\vec{F_1}| = 10$ N, $|\vec{F_2}| = 15$ N and the angle between $\vec{F_1}$ and $\vec{F_2}$ is 60°, then the magnitude of $\vec{F_3}$ is closest to:

Two forces of magnitudes $F_1$ and $F_2$ act on a particle. The resultant force has a magnitude $F_R$. If the angle between $F_1$ and $F_2$ is increased, keeping their magnitudes constant, which of the following is true about the magnitude of the resultant force $F_R$?

The resultant of two forces 3P and 2P is R. If the first force is doubled them the resultant is also doubled. The angle between the two forces is

There are two forces each of magnitude 10 units. One inclined at an angle of ${30^0}$ and the other at an angle of ${135^0}$ to the positive direction of x-axis. The x and y components of the resultant are respectively.

If three vectors acting simultaneously on a particle can be represented in magnitude and direction by the three sides of a triangle taken in order, then the particle will:

The parallelogram law of vector addition is equivalent to which other law for vector addition?

The adjacent sides of a parallelogram are $\overrightarrow A = 2\widehat i - 3\widehat j + \widehat k\,and\,\overrightarrow B = - 2\widehat i + 4\widehat j - \widehat k$ . Then the area of the parallelogram is

If two vectors of equal magnitude act at an angle of 120 degrees to each other, what is the magnitude of their resultant?
