magnitude of vector 2a+3b if a= i+j-2k and b=2i-j+k
2a+3b = 2(i + j - 2k) + 3(2 i- j + k) =5i - j - k magnitude = (52 + 12+12)1/2 = (27)1/2 units
2a+3b = 2(i + j - 2k) + 3(2 i- j + k)
=5i - j - k
magnitude = (52 + 12+12)1/2 = (27)1/2 units
The vector sum comes out to be 8i-j-k.So magnitude is nearly 8.12.
