No. Date Physics. "Vectors" Those physical quantities which require Magnitude as Well as direction for their Complete representation and follows Vector laws. Vector chasified two types. Polar Vector these Vector have a starting part of application Such as diplacement Force. Axial Vector these vector Represent tationnal effect and act along the Axis of relations in accordance with Hgth hand Screw Rule . Properties of Vectors addition. Vector addition IS Commutative, I.e A+B BtA . Vector addition is associative. At (B+C) = B stCC+A). CHCAIB). Vector addition distributive m (A+B) = MAIMB. Ato. . A .
No. Date Addition OF Vectors TRiangle law of Vector. R I B Sino 601 A. IF two Vechor A and B acting ata point are inclined an angel O Resultant R= 1 A2 B2 + 2AB Cos O IF the Resultant Vector R. Subtend an angle B with Vector A then . tan B= Bsin 0 At B Coso 0. Parallelogram law of Vectors addition . B R. o B sinG B 0 A. B Cos 0 Resultant of Vector A andB IS Given By R= V A2 +132 +2ABCos 0 IF the Resultant Vechor R. subtend an angle B with A. tan B > Bsin O At BCOSA
