Question

Transcribed Image Text:A particle, which remains at rest, is acted on by three forces F, G and H.
The force F has magnitude 5 N and is directed to the right and down, making an angle of 70° with the
horizontal.
The force G has magnitude 11 N and is directed to the right and up, making an angle of 50° with the
horizontal.
Find the magnitude of the vector H, and the acute angle it makes with the vertical.
Give the magnitude to one decimal place and the angle to the nearest degree.
The magnitude of His
N (to 1 d.p.)
O
The acute angle H makes with the vertical is
(to the nearest degree).
