Answer 1

${\huge {\mathfrak {\green {Answer :-}}}}$

$<i><b>$ A + B = A - B

=> B + B = A - A

=> 2B = 0

=> B = 0. $</b></i>$

➡️ Option (d) B = 0, is the required answer.

That's it..

Answer 2

I think the answer would be d) B(vector)=0

y.....?

as...

it is observed that a+b≠a-b

untill and unless one of them is zero...

now, a can't be zero as if we keep a =0

then...

0+B(vector)=0-B(vector)

*(↑ not possible)*

now let's try putting b=0

A(vector)+0=A(vector)-0

yeah that's y...
