2.3 APPLICATION OF SCALAR AND VECTOR PRODUCT

Application of Scalar Product Work done PART – B Example  : Soln: = 3 ( 2 ) + 5 ( – 1 ) + 7 ( 1 ) =    6  – 5  +  7 Work done = 8 units Example  : Soln: = 4 ( 2 ) + 9 ( – 7 ) + 4 ( 1 ) =    8  – 63  +  4     Work done  =  –51 units Work done  =  51 units  (by taking positive value) Example  : is displaced from the point ( 1, 1,  1…
