What is the magnitude and direction of the resultant of 4 coplanar forces as follows:
F1 vector = 20 N Due East
F2 vector = 40 N due West
F3 vector = 50√2 N due north west
F4 vector = 20√2 N due south west
A force of 15 N is acting on a particle of mass 3 kg towards north and a force of 20 N is acting on another particle of mass 2 kg towards east. The acceleration of the centre of mass of the two particle system is
A block of mass 30 kg is resting on a smooth surface. Forces of 600 N and 300 N act in north and south direction respectively. The magnitude and direction of acceleration of the block is
