A force "F" makes an angle `40^(@)` with another force "F". The resultant of two forces is

`2F sin20^(@)`

`2F cos20^(@)`

`2F cos20^(@)`

`2F cos40^(@)`

Prove that (sin20^(@) + sin40^(@)) + (cos20^(@) + cos40^(@))=(sqrt(3)+1)cos10^(@)

At what angle should the two forces vectors 2F and sqrt(2) F act so that the resultant force is sqrt(10)F

At what angle should the two force vector 2F and sqrt(2)F act so that the resultant force is sqrt(10)F ?

Two forces, each of magnitude F have a resultant of the same magnitude F. The angle between the two forces is

Two forces, each of magnitude F have a resultant of the same magnitude F. The angle between the two forces is

Two forces of 45 kg-f and 40 kg-f act on a body In opposite directions. What Is the resultant force ?

If f : R rarr R , f(x) = sin^(2) x + cos^(2) x , then f is

Two forces with equal magnitudes F act on a body and the magnitude of the resultant force is F /3. The angle between the two forces is

Two forces F_(1)=1N and F_(2)=2N act along the lines x=0 and y=0, respectively. Then find the resultant of forces.

A cubical block is experiencing three forces F_(1) = 20 N acts at angle 45^(@) with horizontal and lies in diagram plane of the cube F_(2) = 30 N acts along y- axis and F_(3) = 40 N acts in x- direction as shown in fig find the friction force acting on the block if it is at rest
