Solve this: subtract g." RESOLUTION OV VECTORS Figure OA in angle with the and with Y-axis AC A to X and Y 0B in the on X-axis. Similarly OC is the project-im of Y-axis. According to Of we a into OX Other along OY. The Of the part along OX is OB— a cosu and the of • a If and vectors of unit magnitude along OX and respectively, we get so that 0B a i and OC 2 a 2.8 If the vector a is not in the X.Y plane, it may have nonzero projections along XYZ axes and we can it into three parts i.e., along the Y and Z axe. If g, 9, the angles made by the vector a three axes we get . (2.3) a a i a + a COST k where i, j and are the unit vectors along X. Y and Z axes respectively. ne magnitude (a cosa) is called the component of a along X-axis, (a cosß) is called the component along Y-axis and (a cosl) is called the compnent along Z—axis. In general, the component of y«tcr a along a direction making an angle 6 with it We can us h If au the components This is the of magnit resultant 2.7
