If A = 1-Jand B-3i+4j,then the vectorhaving the same magnitude as that of B and parallelto A isi + j)V2 |
|
Answer» For that , vector.. the magnitude should be equal to that of |B| = √4²+3² = 5 and direction should be of A or unit vector of A = (i-j)/√1+1 = (i-j)/√2 so, that vector is = magnitude* direction = 5*(i-j)/√2 option A. |
