Statement I: If `a=2hati+hatk,b=3hatj+4hatk and c=lamda a+mub` are coplanar, then `c=4a-b`. Statement II: A set vector `a_(1),a_(2),a_(3), . . ,a_(n)` is said to be linearly independent, if every relation of the form `l_(1)a_(1)+l_(2)a_(2)+l_(3)a_(3)+ . . .+l_(n)a_(n)=0` implies that `l_(1)=l_(2)=l_(3)= . . .=l_(n)=0` (scalar).A. Statement-I and statement II ar correct and Statement II is the correct explanation of statement IB. Both statement I and statement II are correct but statement II is not the correct explanation of statement IC. Statement I is correct but statement II is incorrectD. Statement II is correct but statement I is incorrect |
