Three forces of magnitude 40 kN, 15kN and 20 kN are acting at a point O. the angles made by 40kN, 15kN and 20kN forces with X-axis are 60 120 and 240 respectively. Determine the magnitude of resultant

Two forces of magnitudes "8N" and "15N" are acting at a point. the resultant force is 17 newton,then the angle between two forces is

Two forces of magnitude 8 N and 15 N respectively act at a point . If the resultant force is 17 N , the angle between the forces has to be

If the resultant of two forces of magnitudes P and Q acting at a point at an angle of 60^(@) is sqrt(7) Q , then P/Q is

A uniform metallic rod AB of length 1.4 m is lifted by two forces P and Q acting along the directions as shown in the figure. If the magnitudes of P and Q are 20 N and 50 N, respectively, find the magnitude and the position of the resultant normal force that acts on the rod.

If the resultant of two forces of magnitudes P and Q acting at a point at an angle of 60^(@) is sqrt(7) Q , find the value of ratio P/Q ?

In a two-dimensional motion of a particle, the particle moves from point A of position vector vecr _(1), to point B of vectors are , respectively, r _(1) =3 and r _(2) =4 and the angles they make with the x axis are theta _(1) = 75^(@)and theta_(2) = 15 ^(@), respectively, then find the magnitude of the displacement vector.
