Calculate the angle between a 20 N force and a 30 N force so that their resultant is 40 N

Calculate the angle between 20 N force and a 30 N force so thea ther resultant is 40 N .

Calculate the angle between a 2N force and a 3N force so that their resultant is 4N.

The square of the resultant of two forces 4N and 3 N exceeds the square of the resultant of the two forces by 12 when they are mutually perpendicular. The angle between the vectors is

If two forces are acting at a point such that the magnitude of each force is 2 N and the magnitude of their resultant is also 2 N, then the angle between the two forces is

The square of the resultant of two forces 4N and 3N exceeds the square of the resultant of the two forces by 12 when they are mutually perpendicular. The angle between the vectors is
