Question

the direction of vector A is
reversed. What
are
the
values of delta A and delta Mod A ?​

Answer 1

Ans:

The value of ΔA bar will be 2A

The value of Δ║A║ will be A

Explanation:

when taking A bar it indicates vector with its direction hence the change will be A-(-A) =2A

When taking ║A║it indicates magnitude of the vector hence direction is not taken into consideration
