A) i + j
B) i ? j
C) \[c(i-j)\], c is a scalar
D) None of these
Correct Answer: C
Solution :
Vector perpendicular to both of the vectors \[i+j+k\] and \[i+j\] is,\[\frac{(i+j+k)\times (i+j)}{|(i+j+k)\times (i+j)|}\] \[=\frac{-i+j}{\sqrt{2}}=\frac{-1}{\sqrt{2}}(i-j)\] or \[c\,(i-j),\] where c is a scalar.You need to login to perform this action.
