Three forces ` 9 , 12` and `15 N` acting at a point are in equilibrium . The angle between `9 N` and `15 N` is

Forces of 5 N, 12 N and 13 N are equilibrimum. If sin 23^@= 5 //13 , the angle between 5 N and 13N force is.

Five equal forces each of 20N are acting at a point in the same plane. If the angles between them are same, the resultant of these forces is

Five equal forces each of 20N are acting at a point in the same plane. If the angles between them are same, the resultant of these forces is

When three forces of 50 N, 30 N and 15 N act on body, then the boy is

When three forces of 50 N, 30 N and 15 N act on body, then the boy is

Six forcees, 9.81 N each, acting at a point are coplaner. If the angles between neighbouring forces are equal, then the resultant is

Two forces of magnitude 10N and 15N act at a point making angle of 60^@ between them. Find the magnitude of the resultant and the angle made by it with the 10N force.
