Question

if the direction of vector Ais reversed what are the values of |
delta vector A| and delta |vector A|

Panchali Dutta · Accepted Answer

In the first case, mod of delta A will give you the magnitude of
change in vector A Change in direction will not affect the result
Hence it will be zero
Second case, mod of A gives the magnitude of vector A Since
there is no change in magnitude, the answer will be zero
