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.

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

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?

Two vectors $\vec{A}$ and $\vec{B}$ are added using the parallelogram law. If the magnitude of $\vec{A}$ is doubled while keeping the magnitude of $\vec{B}$ and the angle between them constant, how does the magnitude of the resultant vector change?

Two forces represented by vectors 3i + 4j and 5i - 2j act on a particle. What is the magnitude of the 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

Two forces $\vec{F_1}$ and $\vec{F_2}$ act on a particle. $\vec{F_1}$ has a magnitude of 10 N and acts along the positive x-axis. $\vec{F_2}$ has a magnitude of 5 N and acts at an angle of 120° with respect to the positive x-axis. If the resultant force $\vec{R}$ makes an angle $heta$ with $\vec{F_1}$, then $an(heta)$ is:
