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

The resultant of two forces, one double the other in magnitude, is perpendicular to the smaller of the two forces. 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 magnitude of resultant is 12 N. Then, themagnitudes of the forces are

Which of the following is the correct order of forces?

Which of the following groups of forces could be in equilibrium?

A mass of 5 kg is suspended by a rope of length 2 m from a ceiling. A force of 50 N in the horizontal direction is applied at the mid-point of the rope. The angle made by the rope with the vertical, in equilibrium is

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

Three forces F₁, F₂ and F₃ together keep a body in equilibrium. If F₁ = 3 N along the positive x–axis,F₂ = 4 N along the positive y-axis, then the third forceF₃ is
