A particle P lies on a smooth horizontal surface. It is acted on by two horizontal forces of magnitudes 25 N at an angle of 30 degree with the horizontal and 20 N at an angle of 45 degree with the horizontal. Both forces acted away from the particle. A third force F is required to keep the particle in equilibrium.
Obtain F as a vector, giving its components to one decimal
