When angle b/w forces are other than then we add these vectors by different methods in which “head to tail” is mostly used. As shown above in fig 5 + -10 = -53) When angled/w forces are other than 00 1800. when the angle b/w any two forces is zero then these vectors will be parallel to each other in this case we add the magnitude of individual forces to get a magnitude of resultant forces as shown.2 ) When forces are anti-parallel I Q = 1800:- when two forces are anti-parallel then, in this case, we subtract the magnitude of individual forces from each other to get the magnitude of resultant forces. Some special cases of the addition of vectors are given below.1) When angle b/w forces are zero (Q=0). The vector we get after the addition is known as the resultant vector. Its weight is “w” in a downward direction while the normal force of the table on the block is in an upward direction, these forces have some line of action and balance each other.(b) In figure “c” two forces “p” and “Q” are shown which are acting at points “A” and “B” these forces are known as parallel forces.(c) In figure (d) two forces “l” and “m” are shown which are acting at points “c” and “D” these forces are known as “ anti-parallel” forces.Q.2 Explain the addition of forces in detail:Ans:-force is a vector quantity and forces can be added to each other by vector algebra. (a) in the earth's gravitation field, the attracts everything towards its centre the gravitational force acting on each particle of the body is parallel as shown in fig (a)(a) In figure (b) two a block is shown on a table.
