What is the resultant of three coplanar forces: 300 N at `0^(@)`, 400 N at `30^(@)` and 400 N at `150^(@)` ?

The resultant of two like parallel forces 5 N and 10 N is _______ N.

The resultant force of 5 N and 10 N can not be

The resultant force of 5 N and 10 N cannot be

The resultant force of 5 N and 10 N cannot be

Two forces A and B are acting at a point . The least and greatest resultants of these forces are 5 N and 10 N respectively . If each of these forces is decreased by 2 N , then what will be the resultant of these new forces acting at an angle of 30^(@) to each other ?

What is the vector sum of n coplanar forces, each of magnitude F, if each force makes an angle (2pi)/(n) with the preceding force?

Find the resultant force of the following forces which act upon a particle . (a) 30 N due east , (b) 20 N due north , (c) 50 N due west , (d) 40 N due south .
