Two forces, 1 N and 2 N, act along with the lines x = 0 and y = 0. The equation of the line along which the resultant lies is given by:

Component of  perpendicular to  and in the same plane as that of  is:

If the angle between the vector  the value of the product  is equal to:

Two forces A and B have a resultant R₁. If B is doubled, the new resultant R₂ is perpendicular to A. Then

Assertion: The graph between P and Q is a straight line when P/Q is constant.
Reason: The straight-line graph means that P is proportional to Q or P is equal to a constant multiplied by Q.

Which one, of the following statements, is correct

Two forces of magnitude F have a resultant of the same magnitude F. The angle between the two forces is 

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

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

If two forces of 5 N each are acting along X and Y axes, then the magnitude and direction of resultant is
