The vector joing the points A(1,1,-1) and B(2,-3,4) and pointing from A to B- (a) -i+4j-5k (b) i+4j+5k (c) i-4j+5k
clearly, OA= i+j-k OB= 2i-3j+4k by triangle law, OA+AB=OB AB=OB-OA AB= 2i-3j+4k -(i+j-k)= (2i-i) + (-3j-j) + (4k+k)= i-4j+5k Therefoe, correct option is (C)
clearly, OA= i+j-k
OB= 2i-3j+4k
by triangle law,
OA+AB=OB
AB=OB-OA
AB= 2i-3j+4k -(i+j-k)= (2i-i) + (-3j-j) + (4k+k)= i-4j+5k
Therefoe, correct option is (C)
